How to ensure audio is NOT being shared with user connecting to my Mac via Jump Desktop?

Mac Sequoia 15.6 - I have my personal Mac user account. And a separate 'mom' account on my Mac. I've set up something for her to connect remotely with Jump, and use something I set up for her on my Mac under the 'mom' user account.

But I want to be sure that any audio/music/podcast/etc. I play on my own user account won't randomly play for her when she's connected. Is that possible to begin with? I'm looking into audio options and on my Jump Desktop version I only see under Settings > Advanced an option for audio capture device which lists Jump Audio and Microphone options, and some old ones for apps I no longer have (Boom Audio, No Machine, Camo). I don't know if these impact the situation I'm describing, but can I just set it to something like Camo Microphone (I no longer have the app for this) and that will effectively block any audio or mic sharing?
