I don't know if browsers detect the paddles, so I'm not sure if I can add support for them to the editor. You should however be able to set the keycodes manually. Just untick "record keycode" and enter the number:

Here's the list of codes:

Specifically the paddles:
SDL_CONTROLLER_BUTTON_PADDLE1 | 16 |
SDL_CONTROLLER_BUTTON_PADDLE2 | 17 |
SDL_CONTROLLER_BUTTON_PADDLE3 | 18 |
SDL_CONTROLLER_BUTTON_PADDLE4 | 19 |
Not sure which one is the correct one, so you'll have to test that.
It might just be that the anti cheat prevents the plugin from working. I don't think there's much that can be done in that case.
