Which components should I install for MS Teams proxy ?

Two main components to install for MS Teams Proxy:

This is the setting in EW settings in the portal (the setting name is EthicalWallTeamScope):

There is a warning message about it on the portal EW settings page:

Parameters for the adapter that must be set:

InitializeMessagingBL = true
EnableFetchingTeams = true
