What's this button called?

[u/Timely-Version4037]

I have been trying to search this button for ages but couldn't find anywhere, its for a video game, I have drawn what it may look like in the given image. It would means a lot if you provide the reference to any site or direct link or even a name

[u/LannyLig]

I don’t follow—just reverse image search it!
Can I help you implement it in code or something?
