How to make "Show more" for comment?

Any suggestions, link to tutorials how to add show more link/button for truncated text (like in image). How does it fits in the auto layout?

First think I can think of is to create a component set. Variant A is going to hold the truncated text, and variant B for the full text. When you click on “read more”, you can change the component instance from variant A to variant B with smart animation if you like. Using a property for the comment content would be practical for future use.

To be able to truncate the text :
Figma comes with “truncate” option for text. You can apply that on the text.

Good luck.
