Hello @Daniel123_,
Congrats on your first post!
I assume you want to know how to connect to another computer and how others can connect to your computer.
There are many ways how to connect. You'll find everything explained in this article:
📄 Connect via TeamViewer
You just need to install TeamViewer on your computer and provide your supporter with your TeamViewer ID and password.
Let me know if this could help you.
