Is it possible to customize and add your own buttons to the vanilla UI of teams?

[puri18]

For example in the contact card or in the organization chart cards, I would like to add some custom buttons that would do their own thing.

Sorry for the rough sketch. But is this possible?

Unfortunately the kind of customizations you are asking for are not possible Today in the Teams Clients

What kind of customizations could we do in Teams then?
