I implemented Authorization Server with spring boot and keycloak using the following dependencies:

```
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson2-provider</artifactId>
    <version>${resteasy.version}</version>
</dependency>

<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-dependencies-server-all</artifactId>
    <version>${keycloak.version}</version>
    <type>pom</type>
</dependency>

```

I defined a client to have **client\_credentials** authorization flow in keycloak admin console. everything is ok and client can get his access\_token and refresh\_token.

Now, i want to be able to revoke this client issued tokens and also prevent his to get new token. how and where can i do that in keycloak admin console?
