JS Scripts not being translated on external Apps

Hey guys, I have an issue I need help with.

HTML files translate correctly when using the proper translation tags, even on external apps.

But when it comes to JS Scripts Modals I’m not able to translated from external Apps.

Example, Webshop App does not translate JS modals, simply ignores translation Tags. For example in the Item Configuration Script and the Enquiry Script.

Is there anything missing on hooks.py?
Do we have to build translations manually with bench or in some other way?

How is it suppose to work?

Thank you!
