There are two ways to create a link that would lead to a certain block (section) within the page:
1. You can target any block with a link that contains the block's ID, e.g., #rec129000. Every block has a unique ID that you can find at the very bottom of the Settings panel of the block.
2. Add a T173 block ("Anchor Link") from the "Other" category of the Block Library. Please set an anchor name for it. For instance, "chapter1." When the page visitors click on the link that contains the anchor's name, they will be taken to the spot of the page where the anchor block is. The anchor block itself will remain invisible.
