Would someone please help me test my screen share really quick??

 So I had to cancel a meeting with an important client today because screen share was not working properly.  This obviously is very bad lol.  We are not sure if it's on my end or theirs.  .    Testing it for a couple seconds would really help for troubleshooting to see what's going on before the rescheduled meeting tomorrow.  Thanks in advance.  🙂
