Default room setting of 'who can read previous history'/history visibility in configuration

**Description:**

I would like to have the abbility to set room preference "Who can read the previous history? -> Invitation" in Configuration Manual as a default room setting.

Thanks in advance.

Start by reading the Configuration Manual and locating how default room settings are currently documented and represented. Trace the existing “Who can read the previous history?” preference, then confirm that the requested Invitation default applies to newly created rooms and is documented clearly.
