I say right away, I’m a complete zero in all this so far, that’s why I’m learning. I'm making a business card site (so far it's just a random template). The site is on GitHub Pages, and the domain (\leomovskii.com) was bought on Google Domains.
In Domains, configured DNS A to GitHub IP addresses (185.199.108.153, 185.199.109.153, 185.199.110.153, 185.199.111.153) and CNAME to www.leomovskii.com.
When the site started working, chrome started to write that the connection is not secure, the site does not have HTTPS.
After poking around in Google, I got a certificate on letsencrypt.org and after some time the chrome warning was replaced by the notification "The connection to the site is not completely secure."

Tell me what I need to do next so that https works fine and chrome does not swear?

In the browser, open devtools and there, in the console section, the reason will be written:

Mixed Content: The page at ' https://leomovskii.com/ ' was loaded over a secure connection, but contains a form that targets an insecure endpoint ' uipasta.us14.list-manage.com/subscribe/post?u=8548 ... '. This endpoint should be made available over a secure connection.

Why not use the official guide?

I'll add - I just read Ilya's answer above - really mixed content.
