[MacOS] Is it possible to support microphone input for screenshare audio?

Is your feature request related to a problem? Please describe.
I'm currently in a situation where Discord recently pulled the plug on screenshare audio for macs older than MacOS 13. I am currently running on MacOS 10.15.7 which previously had screenshare audio support.

Describe the solution you'd like
I have been looking around for third party screenshare audio support and venmic had been the answer for linux support. Having tried vesktop, I am wondering if it is possible to capture Mic-In inputs for screenshare audio. I do not need a full application audio capture feature since I am able to use Loopback to broadcast apps as a mic source. It would be perfect if Vesktop can pick up Mic inputs as a source for screenshare audio.

Describe alternatives you've considered
I have been searching afar for mac support for screenshare audio. However previously Discord had great support for MacOS audio screenshare such that a need for third party audio support is not needed. It is only recently that support has been removed for older OS such that alternatives are not yet available. Currently, Google Chrome may cast audio for chrome tabs, though not individual windows outside of Chrome.

I would be in favor of venmic support for macOS, not just for older version support, but because the official desktop app requires you to install a system extension for audio sharing. On M1, this is not intuitive at all as it requires you to reboot your system just to install it. Perhaps Vesktop could capture audio on macOS in a way similar to how OBS does.
