opening a webpage while still in Zoom

I have to take a tech test to see how well I know Zoom. First, I start the video, then I write my name on the whiteboard then close the whiteboard. Then, I "open browser, go to www.google.com, and share this screen. I can't find a way to open a browser from within Zoom. Then, above the Google logo, I'm supposed to use the "annotate" function to draw my name. I just can't find a way to open a browser while I'm still in Zooom. Obviously, the recording is so I can prove myself. Please help.
