How badly are users forced into using Ionic Premium paid features?

I’m taking a peek at Ionic to see what it’s all about.

My current tech stack is Vue + Netlify + Fauna + Auth0.

Can I realistically incorporate Ionic builds without using their premium paid features?

For example, how easy and realistic is it to continue using my current Auth0 setup along with Ionic. Will I be forced into using their paid Auth feature because other solutions don’t play nice?

Same question for using Netlify instead of Appflow, Fauna instead of Ionic Secure Storage, etc.
