Can not see integrations configuration in my projects on on premise sentry 8.8.0

When I list integrations (plugins) on command line I get 2 plugins but I do not get any integration on projects settings:

You need to restart all services when installing new dependencies, as the Python runtime exists primarily in memory and won’t pick them up automatically.

After removing following lines in sentry.conf.py:

SENTRY_FEATURES = {}
SENTRY_FEATURES[‘auth:register’] = True

All integrations appear again.
