Replacing wing mirror glass (KIA SEDONA)

Bought a new wing mirror glass from Kia to replace the one I broke.

Got the old one off with the aid of a scrwdriver but having a job
getting the new one back on. Anyone every done this?

Seems well difficult - there are four clips at top, bottom, and both
sides but its difficult to clip onto the door mirror internal bit
because this moves around a lot when you're trying to do it....
