Your link worked, you might want to look in another community to ask the question or find another post of how you wanted to post it and ask how they linked the tweet. It also might be something that is in development to. It looks like you did create a post, then provided the link. I don't see any other options. There is a also a bot on Mastodon that mirrors the Packers twitter. That might give you a different way to generate the link. Sorry I don't have an exact fix.
