how to reactivate the application

I can still see the files but I no longer have access to them.

Hello @Denis NOUAILLE DEGORCE 

For how long you weren't using your instance? If it was more than 120 days, Atlassian needs to reactivate this for you. I can see that you have apps listed, do you have an option to reactivate when you click on three dots under Actions part?
