Additional Indicator in Participant Element (remote and local video container)

Hello Community,

I want to add an additional UI element (icon) in the participants containers which shows which Browser the participant is using. Does someone know in which files I have to add the code to get information of which browser is used and create the additional indicator element to create the additional element in the remote/local videocontainer_toolbar.

Also in which files would I need to add the mappings for the new icons?

Hope someone can help me.
Thanks for your time.

Greetings Tom
