A text animation tool or plugin pack that has very elaborate text animations?
If you don't want to do your own animations, you might want to search for Essential graphics presets. Essential graphics allows you to load AE compositions inside PP ready to edit like the ones you have seen. There are a bunch of places where you can get them, for free and paid, like Envato Elements, Premiumbeat, Mixkit, even Youtube itself.
If you want to know more about it, here's a link to Adobe's wiki for &quot;Essential Graphics&quot;: https://helpx.adobe.com/es/premiere-pro/how-to/essential-graphics-panel.html
