How to edit a 'text note'?

Help
1

Is there a way to edit an ‘inserted text’ after I have closed the text window?

Also, Is there a way to move the inserted text around in the document?

I vision something similar as the ‘cell comment’ in Libreoffice “Calc”.

Is that possible?

I’m using Okular v 25.08.2 (flatpak) on Linux Mint

Thanks
