What is a handy screen share program?

Question

Work organization

Good day! The other day it was necessary to find how to set up the simultaneous display of two screens in Skype when two users are talking. The main thing here is SIMULTANEOUSLY, since when two users are talking, when user A shows the screen, and user B turns on the display, then the display stops for user A. The question is how to set up simultaneous display of two screens in Skype, or what are some worthy alternatives to it with this feature? At the same time, the possibility of transmitting messages and talking is obligatory.
