In DSE, we can create role with password and specify whether the role is superuser and can login. Then we can use that role with password to access DSE resources. But in ASTRA, it did not allow me to specify a password. How do I use a role in ASTRA to access ASTRA resources, for example to do DSBULK. I am able to do DSBULK with the client id and secret, but I wanted to do the DSBULK with a specific role.
