Hello,
I added by curiosity a PowerApp form in Sharepoint doing like that and publishing it :

It is now impossible for me to delete it. I am wondering if I have to delete the whole list to start all over again to get rid of this form...
I tried this, but I don't have the "Form Settings" in my List Settings page.

The thing that is the closest is this, but it does not work:


If I go there to list all the applications, it seems that it does not exist and I cannot delete it:


Can you help me finding how to delete this Form please?
Thank you
