How to send an image to a group in groupme?

I know to send an image through groupme, I need to upload the image to groupme’s image service so I can display it properly. But if I’m being honest, I can’t figure this out. Any and all examples are shown using python bots, but it’s hard for me to visualize what code goes where in regards to Make’s UI.
I was using the GroupMe “Make an API Call” scenario, but I dont know what to really fill in where. I already have my image link, my link just isn’t from groupme’s image service (it’s from a google calendar attachment, usually a picture from google drive).
