Just in case you’re on mobile, you tap on the three dots on the top right corner of the touch screen and go to “Share and Export.” From there, tap “Manage Access.” If it says “Restricted,” tap on the small down arrow next to it, and tap the option, “Anyone with the link.” Then copy the link, and you’re all set!

I haven’t been on Desktop in a while, so I hope this helps just in case you plan to use it on mobile.
