Hello, I am trying to learn using generateblocks to customize a library site. May I learn how to delete a block in the theme. And how to add a new one. Its quite confusing to me. And I also want to add a whatsapp link on the page, I coudn’t find how to do it. Thanks a lot.
The best way to make changes to a complex page in the Block Editor is to open the List View ( 3 bar icon in top bar ). This will allow you to more easily select blocks that you can choose to Remove ( same as using your Delete key ) or Insert Before or After a new block.
