One of the first options that open many doors is power automate, you add a lot of functionality that might make the transition easier.

we have one client that uses teams and basically uses power automate to repost all the messages to slack. So the MS side and the slack people both get what they want out of it.

There is a vast array of prefab templates

You can also do most of this via graph if you would rather, but I find both to be bit painful to deal with, with power automate the infrastructure is provided so there is that, but its largely designed to be a no code drop block style environment which limits its functionality.

Graph will give you a lot of control, and allow you to create things in a consistent manager, but the management of it, and time to develop often out way the value of the functionality.
