Set default dictionary at Thundebird snap install


How can I install and set an default dictionary in snap Thuderbird?

I have a script to customize and install Ubuntu in my office, and on 20.04 Ubuntu version I copy the Pt_BR dictionaries files at /usr/lib/thunderbird/dictionaries. So when a new user log in at the machine the dictionary for our language is already available in Thunderbird .

How can I do this in Ubuntu 24.04 that uses a snap installation?
