Site24x7 integration already allows different teams to be alerted to different issues through a combination of User Alert Groups and associated Attribute Alert Groups.  The Microsoft Teams Connector integration however is to Site24x7 as a whole.

This means that all alerts are sent to the connected Teams channel.  It would provide significant benefit if the connector was linked to a User Alert Group so that different teams can be alerted to different issues as they can via email.

You can configure the Teams integration to only be linked to specific monitors but those monitors are likely already linked to a User Alert Group so this doubles the administration effort.  The only other filter option on the integration is by tag.  Monitor groups are not even an option requiring potentially hundreds of monitors to be selected and constant administration effort as changes are made.   Linking to the User Alert Group would make this much easier.
