Problems connecting a system managed account (hosted on azure account automation) to a storage account?

Question

Hello community, I have a problem connecting a system managed account hosted on an azure automation account. with a storage account. Basically what I want is to connect and bring me the access key but it is generating an error of a permission that was already given, but the account continues to generate the same error. Do you know how I can make the account delete cache or reload the permissions, although in the permissions section already appears.

I am using PowerShell. I remain attentive to your comments.
