Replacement lens for Fireflies PL47g2?

So the bezel on my PL47g2 came loose, and when pressing it back on, the lens cracked. So, where would one find a lens that fits? Only directly from Fireflies? Or will a generic lens that size be fine? If so, what size and where should i order, preferably in the states?

Measure the lens dimensions and look up an AR coated lens on AliExpress.

Maybe the Convoy store has something adequate.
