Shared projects with external DB and local CVAT

[mbspng]

Does the "organizations" feature work with a local CVAT instance? How can I share a project with others? We are hosting our own Postgres DB and have connected that to local CVAT clients as by https://docs.cvat.ai/docs/administration/basics/installation/#deploy-cvat-with-an-external-database

Now we need to get several users to be able to view shared projects on that database. I am at a loss here. I suppose it needs to go through the "organizations" feature. But the documentation is lacking here. I have managed to get the local client to SEND an invitation mail, and it actually arrives, by modifying cvat/settings/base.py with the following code and settings up a Gmail account with an "app password" for this, but the invitation email that arrives in non-functional. When pressing the accept button you end up at example.com and there are also not invitations arriving at the recipient's local CVAT client... well, how should they... So... can this be made to work? If so, documentation needs to be updated.

EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
EMAIL_HOST = "smtp.gmail.com"
EMAIL_PORT = 587
EMAIL_HOST_USER = "<...>@gmail.com"
EMAIL_HOST_PASSWORD = "<app password>"
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False
EMAIL_TIMEOUT = 10

If this does not work, is self-hosting the client rather than running it locally an option to get shared projects working?
