[keycloak-user] Managing user from my java backend

[Juan Diego]

Hi

I want to manage my users from my app but I dont understand some things.

My backend is on java, front is on angular. So for my backend I used client
of Type Bearer Only.

I was looking at this example
https://github.com/keycloak/keycloak/blob/master/examples/demo-template/admin-access-app/src/main/java/org/keycloak/example/AdminClient.java

And this one
https://gist.github.com/thomasdarimont/43689aefb37540624e35

So my question is

Should I create a User in my keycloak server for my app to use?
 Or should I use another type of client?

Can i connect using just the client credentials? I thought I will have use
the secret in credentials and the token there to connect?

Thanks
