Pro-test is available. Long time no see. Would you like to order before sharing the screen? Don't choose the built-in speaker, then open the qq screen to share, and then switch to the built-in speaker after connection, so that your voice and the video sound in the computer can be heard by the other party. I don't know how it works, but it can be used anyway. PS: My qq version is 6.6.0, and then the system version is 10. 12.6.
