Change the 'Add Section' text per layout paragraph type?

Hi can you give me more details about it ?

I mean the text that is displayed in the layout paragraphs field when creating new content. For the most part, Add Section is perfectly fine, but there are some occasions where I would like to change the text, e.g. where each layout paragraph section is a slide in a carousel, then I would like to change the text to Add Slide. See attached pic to see the text that I would like to be able to change.

You should be able to customize the label by implementing hook_preprocess_layout_paragraphs_insert_component_btn($variables). I would start there and see if that gets you what you need.
