*.brain files 3.18.5 - Open with - add (application)?

[83102347810943780914327097814]

Hello,

I like to open in /Documents my file *.brain with TheBrain.

PB7 can be started via the terminal...
/rw/usrlocal/TheBrain/TheBrain

I open the files 3.18.5 and found the help, which explains how I add a new application:

1. choose file ... *.brain
2. open with
3. press the button ADD

But this button is inactive...

What I must do that I can press this button?

Kind Regards

Hello,

With the q-menue sync command I can bring the new app into the VM application menu:

1. start VM
2. terminal dom0
3. qvm-sync-appmenus vmname

This works fine.

But why nautilus / files 3.18.5 open with applications menue is not in sync afterwards?

I would expect TheBrain Icon, run this file under the application...

Kind Regards
