A working way to remove entities and integrations

I know there is a supposed way to do that right now, but it doesn’t work. Integrations trash button don’t do nothing and removed entities keeps showing.

Do you hav news about this ?

It doesn’t look there will be changing something if this problem exist already a year. I have the same problem, entity you don’t want or you don’t have anymore, devices who are gone for a long time. You can delete them hide them ignore them or remove them. They always come back it’s a complete mess.
