Different Widgets for Language in Customizer / Copyright

I have a multilingual website with Polylang.

In the customizer under copyright I want to use different widgets (widget A for language A and widget B for language B).

I use the Plugin Reusable Gutenberg Blocks Widget (Display Gutenberg saved reusable blocks anywhere via widget) and the Plugin Widget Shortcode (Output widgets using a simple shortcode) .

In the copyright section these plugins don't work. What could be the reason?

But maybe you have another idea how I can display two different html-codes for two different languages in the copyright section.

With Elements I can't find the Copyright section.
