Undo tccutil reset

[MacOS 13.3.1 Ventura]

Some time ago, I installed a chat app on which I didn't expect to use voice comms, so I did not allow it permissions to access my microphone at the time. Yesterday, though, I needed to use the microphone this app, but the app was not listed in the Privacy & Security -> Microphone list, so I was not able to flip the slider switch to enable it.

After trying some things to make this chat app ask for permissions, including restarting the app, I decided to see how others dealt with this issue by searching the web. Amongst the advice I saw was a reference to a utility called tccutil where it was suggested to use the command: tccutil reset Microphone. It was explained that the command would reset all the permissions for the microphone and therefore force apps to ask for permissions again. So I executed this command in my terminal and saw that the entire Microphone permissions list was scrubbed. I didn't think much of this as it's essentially what I was expecting to happen.

However, when I relaunched my chat app, I was not prompted with a permission request. I found this a bit strange and tried some of my other chat apps I have which I use the microphone reguraly; namely Discord and MS Teams. To my dismay, these apps did not ask me for permission to access my microphone, thus, as things stand right now, I am unable to use my microphone on my computer.

How can this problem be solved? Is there some commands or places in System Settings which allow the owner/administrator to manage these settings? Alternatively, is there some documentation that explains how to manually manage the privacy database that tccutil reset?

I have seen some advice on this issue, to do with League of Legends (which I don't play), but in that case the problem was that that user's client wasn't coded to ask for permissions in the first place, so the permission needed to be manually given. I don't mind doing this, but it appeared to me that some detail information was needed to enable this which I am unsure of how to find/determine.

Any help with this problem would be greatly appreciated.
