Hello, as far as I know, there are a couple of ways of doing it... : )
The short-cut, & way that I usually use - if of the, "copy & paste~" variety--or 'method!'
(which is what I did here ^ up above. . :^))
Or: if you go up to the top column, and click on the three dots, "..." w/the arrow pointing down below, it will say, "insert~!"
. . . & then proceed to give you some options, of which, the first is 'media."
If you click on that, and then follow that path, or route, you get this--> ; )
(just let me know if you have any questions as I am terrible at tech & probably may have just explained something, incorrectly; or not-quite-right!)
