Removing 3rd party apps' data from teams ?

Hi,

I installed a 3rd party app in teams, had an issue with it (error 500), remove it and reinstalled it but this time the 3rd party app is not asking for signing in and when the app is opened it starts loading and shows (error 500) again.

Can I know where is the data for 3rd party apps stored in Teams or how to remove 3rd party app data in Teams ?

Thank You
