SCOM 2019 - configure web console to use SSL AFTER installation ?

Hi everyone,

a client installed SCOM 2019 + UR3. He uses the web console with HTTP and wants to use HTTPs now. Any article/documentation related to this ? I only find docs related to SCOM 2012/2016 that are out of date - most of them mention a webhost folder that does not exist anymore.

I tried to configure it and whenever I connect with HTTPs, I get an authentication request, event if my account is SCOM admin.
