ADAT (Behringer Pro-8 Digital synced to Scarlet) output from Scarlet 18i8 2nd gen not registering in OBS but does in DAW?

Hello, I have an issue that I cannot figure out and was hoping the community could render some assistance. I have a Scarlett 18i8 2nd gen, that accepts ADAT input. Input to the Scarlett, via ADAT in, is a Behringer Pro-8 Digital ADAT converter that expands the number of mic XLR inputs. It would appear that I have everything properly configured because the microphones from the Behringer input properly to a DAW and I can record just fine. However, when I'm using OBS, and I select the Scarlett as the audio source, only the mics connected to the Scarlett input to OBS and not the one's from the ADAT converter. In Focusrite Control, I can see the Behringer mics are registering, but they are not producing any input to OBS. I've looked at every angle with the Scarlett and the Behringer and have determined that the clock source is correct, they are syncing, and the input/output routing appears correct. The reason I say it's correct is that (as stated earlier) I can use the Behringer as intended with any DAW. Can anyone with experience with these devices, or my setup in general, offer a suggestion as to why it works as intended with a DAW but not with OBS? Thank you.

Update: I was able to figure this out with the assistance of an amazing rep named Ryan from Focusrite. In the unlikely event that anyone else experiences this issue, I will share the results here. There are two solutions.

1. Solution Number One: Install the OBS ASIO Plugin and then assign each mic from the ADAT unit as an ASIO Input Capture in an individual scene. Select Focusrite USB Audio as the input device and then select the appropriate Channel (Like you were doing it in a DAW). In this solution, the regular Analog Focusrite mic inputs can be included in OBS in the usual way as a mic/aux source and they will be global. However, you will not have the ADAT mics included in that mix nor will they be summed and available as any global audio source. The ADAT mics will only be assigned individually to each scene. If you want them to be global, you'll need to assign the same ASIO Input Capture to every Scene. I imagine that if someone wanted to use a mic as a scene trigger, then this would be the best option.
2. Solution Number Two: Create an S/PDIF loop with a patch cable on the back of the Scarlett by going from the S/PDIF OUT to the S/PDIF In on the same unit (the S/PDIF cable looks like RCA but is coax and capable of carrying both analog and digital signals). Then you assign S/PDIF as the output in Focusrite Control. Then you expose the loopback channel via the Expose/Hide Windows Channels feature in Focusrite Notifier. With this solution, all of the analog and digital mic inputs on the Focusrite unit and the ADAT unit are summed as a single global audio source called the "S/PDIF L + R (2- Focusrite USB Audio) " in OBS. You will still have the option of selecting the Analog 1 + 2 (2- Focusrite USB Audio) as a source, but you won't need it and don't want it because it will just double up on and amplify the analog inputs.

Hopefully, if anyone else encounters this issue in the future, this solution will be available for them to find here on the forum. On a final note, I wanted to give a shoutout to Ryan and the customer service team at Focusrite. I have to say that's some old school customer service shit they delivered for me. Amazing service, especially considering I purchased my Focusrite used from Reverb which places me somewhere downstream in the paying customer flow. But, that's how it should be and when I purchase new, Focusrite will be my go-to supplier.
