You are not going to be able to (or want to) give your client side app the ability to get all users from the management api. You will want to do this in your backend. Take a look at this FAQ for some more info about why: How do I use the Management API in my single page application?
You can also get all users without a number limit using a long running export job, which will return a file in JSON or CSV format: Auth0 Management API v2
Alternatively, you can use the Import/Export extension: User Import / Export Extension.
Does this answer your question?
Thanks,
