paperless-ngx : how to set a new user on UI ?

[Eris76]

Just installed community-script paperless-ngx.
Root user is ok and you can reset password from LXC console with passwd
However when entering GUI in http://x.x.x.x:8000 I don't see how to recover default credentials or create a new User ?
thanks

run update from LXC console until Credentials
