Icon with a button?

[Marine_Farge]

Hello everyone!
I’m designing a mobile interface and would like to put icons like this at the bottom of the page. I have several questions about this:

• Is it called button or icon?
• What nomenclature to give in Figma? I know that for buttons I do buttons/primary/default
• How to choose the vertical spacing between my icon (20x20 px) and my text (12 px)?
  Thank you all for your answers!

The button is a thing you press. The icon is a picture. Icon can be a part of a button like in this case. So it’s a button with an icon and text. The current spacing looks fine.
