How to get cell content to clipboard?

Question

Google Sheets

There is a cell with data that often has to be copied and pasted into another (not related to Google Spreadsheets) document. I came up with the idea of ​​a script that is launched by clicking on an image located on top of a given cell, which would copy its contents to the clipboard. Everywhere where I searched it says only about copying to the final cell or range ... I did not find anything about the memory buffer.
