I am running Gravitee 3.9 in Docker containers (apim-portal-ui, apim-management-ui, apim-management-api, apim-gateway).
No matter what I do I am unable to make buttons for authentication via external identity provider appear at the sign-in screen of portal-ui, although I can see them at sign-in screen of management-ui. How can I make those buttons appear at the portal-ui too?
Observations:
When I go to "Organization Settings/Authentication", I can see that both of my Identity Providers are Activated, they are also ticked in the column "Available for Portal" and button "Show login form on management console" is also ticked.
When following the official documentation, there are also pictures showing "Settings/Authentication" section, but this section is entirely missing from my management-ui (it should be between sections API Quality and Categories, but there is nothing there).
You would also need to enable the setting under Settings -> Portal -> Authentication. See the image below.
