Using ejabberd 18.06, I configure like this:

acl:
  admin:
    user:
      - "user1@localhost"

access_rules:
  configure:
    - allow: admin

commands_admin_access: configure
commands:
  - add_commands:
    - user
    - get_roster
    - sasl_auth
oauth_expire: 3600
oauth_access: all

Then I register the account user1@localhost and visit the page
http://localhost:5280/oauth/authorization_token
filling the fields with user1@localhost and its password.

And the page goes to
http://localhost:5280/oauth/authorization_token?access_token=MBWAlXZy3rzBLII8L74iCm0UlxlElyB5&token_type=bearer&expires_in=31536000&scope=&state=
