I’d like to know as well…
I found it - on my apple, I went to edit my profile in TS, then put the cursor at the end of my screen name, gave it a space or two, then clicked (edit)(emoji), and selected the bee.
I tried it on my PC yesterday, and didn’t seem to find a bee emoji. Not sure why Bill Gates hates bees.
I just copied the bee above and pasted it into the "Display name" field in my profile.
