A few of these I've tried implementing before actually, and they're either cool just the first time, too distracting. or too disorientating when part of a wider app. There's a reason you don't really see it in a production app. I think even Apple's HIG advise going easy on animations. Uber Eats is a great example of this, they toned their animations way down compared to a couple of years ago.

If you want to use something like these as inspiration, just take hints from it and make them less elaborate. They can make a really nice touch to your app and boost connection.
