I haven't found way to add an another role using UI.
First of all, I tried to edit manually /opt/jboss/wildfly/standalone/configuration/drools-roles.properties file and added the required roles to admin user like this:
this way "rest-all","kie-server" were added to admin user, but as groups, NOT AS ROLES.
Second, rolled back the changes made by first way and tried to use kie-config-cli-6.4.0.Final-dist. When I run ./kie-config-cli.sh the result is following:
>>Please enter command (type help to see available commands):
help
Result:
