QUI Presentation Clicker Pointer,2.4GHz Wireless Presenter Remote Presenter Clicker for PPT, PowerPoint Presentation Pointer

I don’t understand how to insert the receiver into the usb port on the computer. it’s so thin and flat, doesn’t stay in the port. what to do?

Will this work on a chrome book and google slides?

Can I use 2 presenters at a time?

Will it slowly scroll vs page up or down?
