Need help with cranks and power meter options

I’m wanting to put a crank power meter on my MTB.the problem is that I am getting no overwhelmed with all the info and could use some help.

I have a diamondback release 4C with a truvativ descendant 6K crankset (specs say chain line is 49,52mm).

I found this SRAM XO eagle AXS transmission power meter with the right chainring configuration and crank arm length, but my question is if this will work because of the boost spacing (still trying to get to rap my head around this concept for cranks). The specs say that chain line will be 55 mm.

Will this be okay or is this not a valid option?
