Shopify Theme App Extension - Locales customization

[pawel_experify]

Hi.
I am developing Theme App Extension for my custom application. Let's assume I would like create some chatbot which will be exposed as a floating button "Chat with us". 
I am using "App embed block", and I have put several locales files into "locales" directory. So far so good, but here I am struggling with one thing. I would like to let me customers (merchants) modify the button copy - instead of "Chat with us" to, for example, "Talk with us" (in case en locale).
Sadly I read in the docs (https://shopify.dev/docs/apps/online-store/theme-app-extensions/extensions-framework#file-structure)

Note: Merchants can't edit the strings in theme app extension storefront locale files.

Is there any way to bypass this limitation?
