On a mission to build a plugin as a newby

i want to build a plugin that allows users to take a pic using their external camera. this capability should be possible since bubble already employs ziggeo, which allows users to take video using their external camera.

this plugin would be great for setting up a profile pic or to share photos.

can someone tell me what coding language is used by bubble plugins?

i would like to research it and try to learn it so that i could build a simple plugin that lets a user take a pic with their device’s camera.
