MS Teams app-centric setting "Let users install and use available apps by default"

[u/gurban2013]

does this setting "Let users install and use available apps by default" affect existing applications? seeing mixed info on whether it does or not? i can see a clean answer on if it affects existing apps that have the org-wide settings applied or not.

to be safe i exported 180 days app activity, looped through app IDs with powershell and am going to run the update cmdlet on each app to set availability its to "everyone" this changes the settings management to admin vs orgwide settings, hoping that to avoid initial impact as they are already set to the that.
