Install via Portainer: TRASH is not enabled

[eaxode]

I've succesfully installed some BareMetal Installs. Today I installed via Portainer (without docker-compose) with a tweaked .env and .yml on a Pi400 with a sepeate /home.
docker-compose.env.txt
docker-compose.yml.txt
Although I enabled the TRASH (PAPERLESS_TRASH_DIR=/usr/src/paperless/trash) and made the bind, it does not save deleted files to /home/tg/paperless/trash.
While searching I manually created /usr/src/paperless/trash and /usr/src/paperless/media/trash in the container, but nothing goes there either.
Where do I change which lever to activate the trash?

BTW: I had to set the first user inside the container with python3 manage.py createsuperuser

Oooops, sorry, wrong paperless
