How to Integrate a WinForms Application with MS Teams?

Question

Windows Forms

There is a desire to create a winforms application that connects to ms Teams through the library. So that a logged-in user can, for example, open a new call or conference. I know that for this it will be necessary to connect the Framework Graph. But the description is so incomprehensible that, in principle, the very beginning cannot be implemented - it will connect to MS Teams. Does anyone have any ideas how to do this? Thanks in advance.
