Go to edit profile page. Some are putting the bee in their profile name (Cletus) and others in their bio. I may move mine to the profile name. Anyway, on a windows keyboard mash the windows key, then the period key and it will bring up the emojis. Type "bee" and you'll see it.
I got a really weird-looking bee when I did that. So I tried a ‘bee’ search and found one that looks like yours, copied it, and tried to paste it after my display name. Didn’t work. What’d I do wrong (besides everything, LOL)
