How to get IDSC admin access

Summary:

Hi Team,
Can You please let us know what are the steps required for giving admin access in IDCS.
Ex. We have created a user in OSC and the same user has flowed through in IDCS but currently its not having admin access.

We have users from the client side who have access to the IDCS site, we just need to tell them the steps to give our user admin access.

Can You please tell us the list of steps or rolls??
