Default Mail App for EagleFiler

Normally we set the default mail app via the preferences/general in the iMail app (the default mail app for Mac).
I have designated airmail as my default app and it works properly on my Mac.
But not for EagleFiler.
When I open an email in EagleFiler, it opens the default Mac App “Mail”

Is it possible to use the default email app I choose ?

This is because macOS has separate settings for the default app to write a new e-mail (mailto:) and the default app to open an e-mail file (.eml). To change the latter, you can use the Always Open With command in EagleFiler.

Thanks a lot: It works like this !!
