Assuming it is the FlyingIron P-38L, [which had an update on Dec 21, 2021 that may take 6 to 8 weeks to turn up on the Marketplace]:
In File Manager, search your Community folder for FlyingIron, and or P-38 & see if anything turns up there.
Also check if you have a FlyingIron A/C in case you got it from them.
