Permissions to only create Cases and HoldPolicy and HoldRule

I want to provide some of our staff the ability to only create a new eDiscovery case (New-ComplianceCase), and a Case Hold Policy (New-CaseHoldPolicy) and Case Hold Rule (New-CaseHoldRule) via PowerShell. Before I start digging into the documentations wanted to ask if anyone knows what permissions and roles are needed to allow only these commands?

For a little more context, when we separate a user from our organization I want to create an eDiscovery case and place said users mailbox and OneDrive site on compliance hold. The "Compliance Administrator" and "Compliance Data Administrator" are more permissive then the admin staff performing these actions needs so I'm looking to limit it.

Thanks!
