As a free open-source thing,
there also isn't support staff, account managers, etc.
Ask your IT Department if they have any gamers on staff... if yes, they will likely be familiar with livestreaming and quite probably OBS Studio (I heard about it from my son)
HOWEVER, beware that typical security controls in a regulated environment (bank, healthcare, etc) will often have reasonable heartburn (if not outright refusal) to consider Free, open-source software (FOSS). First thing I'd recommend you do is talk to your CIO/business partner (or CISO if you have such a dedicated team) and see what IT security policy is on FOSS.
Further, as an Enterprise Architect, if you came to me, I'd suggest there are probably much simpler, more secure ways to accomplish what you are asking. Especially if you use the same video conferencing application for all such 'talking to the customer'. The major 'web conferencing' applications like Zoom, Teams, etc all have ways to directly incorporate Static (picture) and Dynamic (video) backgrounds
- but realize some customers may well be very distracted by a video background.. think recent movies/previews, etc that warn about strobing light effects for some viewers [modern inclusive, consideration of neuro-atypical audience]. I'm not going all woke (far from it), just a recognition that your Marketing team may have some good insight on content to avoid in such a background
