Support add-in in mobile

Question

We are working on creating of Add-in for the Outlook. And there is a requirement to make it work in mobile. Read some articles https://learn.microsoft.com/en-us/javascript/api/manifest/mobileformfactor?view=common-js-preview and https://learn.microsoft.com/en-us/answers/questions/1275940/how-to-fix-the-mobileformfactor-outlook-add-in-man , but they didn't help. We got the error during add-in installation

It seems the MobileFormFactor section is not correct but don't see a way of fix
