Are you doing this on mobile or desktop?
You can check the URL, make sure it is short (Clicking on the date usually goes to the root URL) and copy that URL.
Don't go to the link that says embed tweet, it won't embed correctly and if you copy the embed code on that page. You can copy "link to tweet" but you have to wait a bit for it to embed because it's a funky url.
For example your link should look like this: https://twitter.com/agsuduiko/status/1417133186635599875
