I know this post is old, but if someone finds their way here like me, I have posted my solution. I have created a PCF component that will do exactly what @Vishal1 is asking. I am attaching my solution for anyone else to use. The component has a button with a "copy-icon". On select of the button the text inserted in the parameter "CopyToText" will be copied to the users clipboard. In the "CopyToText", you can add a variable, a label.Text etc. I have made a short video as well.
What I am struggling with is, that I would like to add the option, that after the copying to clipboard has happened, I would like to make a "notify" function, so that the app would notify the user of "The text has been copied to your clipboard or something like that, but till now I have not figured out how to do this in my index.ts file.

Furthermore, I cannot seem to get my control size to fit my button size... both is no issue, only nice-to-have features, so the control is fully functional as is. Would love someone to help me fix the last two issues though, so please feel free to comment.
