The how-to should be explained here https://wordpress.org/support/article/page-jumps/.

Second heading

Filler text

Third heading

The url for third heading should be the post + #third-heading. What sucks about it, that nothing about this is automatic.

Of course again manually for every paragraph with varying degree of ugliness.
