11 speed crank, 12 speed chain?

I'm looking to fit a Sram 12 speed AXS etap groupset but want to keep my FSA POWERBOX 11 speed crank fitted.

Is the crank compatible with a 12 speed chain and Sram 12 speed front derailleur?

Thanks in advance

It's a world away technologically, but I run a 10 speed chain and cassette on my old steel bike, with the cranks and rings it got when I upgraded to 6 speed in 1995. No issues at all.

Yes, I don't see why not. Might not work officially but I don't see why it would be an issue. 12sp chains are narrower externally but what won't affect the chain ring
