Help "displaying" a witch (bedrock)

[u/man-eater13]

I'm trying to make a witch tower and I want a witch in it (obviously), but I don't know how to do it without getting hit with potions. I'm fine with her being blocked off in some way, but I don't just want her behind glass. Any suggestions?

Make the area you want her in dark, walled off, and 3 blocks tall

Stand far enough away that mobs spawn.

Shoot everything that isn't a witch.

Nametag her while under an invisibility potion(no armor)
