GVR circular progressive bar

I don’t really know how to start it. I want to add circular bar on my pointer in VR game.
Something like that. It replaces click after few sec. I just want to do this animation.

How should I start? Is any recommended way to do this?

Follow the tutorial in the link below. Remember to put it in a separate canvas and set it’s Render Mode to “World Space”…then hook it up with your script. You will need to play with it’s transforms i.e set it’s width and height e.t.c.
