Sharing a *.kml file with app Maps.Me

I produce a kml file via app PlanningMotion.com and I download it on my IPhone 8 (iOS 16.6).

In FILES, I find the downloaded kml file. I open the file and I click the SHARE icon (found in the lower left corner). Then I can send a copy to friends via text message or to one the apps suggested. MAPS.ME is not found amongst them…. And There is no way to add it.
