To link to a part of the page directly, you will need to find the block ID of the section you want to link to by using the developer tools and inspecting the code of the page. Then make a full URL with that block ID.

Eg in this example the URL would be: https://super.so/#block-58b91a98a5b146e5a54791ac350ddbf9
