How to share screen using Pidgin and Sipe plugin?

Question

Skype

Hello! For a long time I was looking for a solution to this issue, but the search was unsuccessful. It is my job to use Skype for business, but Microsoft policy does not allow me to live comfortably using Ubuntu as my OS. I installed Pidgin and the Sipe plugin, after which it connected normally. At conferences, if someone fumbles the screen, then remmina starts up and everything is OK. But, if I want to share my screen, then first a request is sent for a long, long time, after which a message is displayed on the other side stating that the equipment is not configured correctly. Actually the question is, how can you fumble the screen with such inputs?
