@Vocal Star Welcome to Microsoft Q&A, thank you for posting your here!!
You cannot revoke access to that particular user in Azure Storage Explorer.
However, we can revoke access of that user on the Storage accounts. if that user is accessing the Storage account through Azure AD credentials, SAS and Access keys.
For revoking user access on a Storage account when accessing through Azure AD account
Remove the role assignment on Storage account resource.
- Open Access control (IAM) at a scope Storage resource, where you want to remove access.
- Click the Role assignments tab to view all the role assignments at
- this scope.
- In the list of role assignments, add a checkmark next to the security principal with the role assignment you want to remove.
- Click Remove.
- In the remove role assignment message that appears, click Yes.
If you see a message that inherited role assignments cannot be removed, you are trying to remove a role assignment at a child scope(ie. at Storage account level). You should open Access control (IAM) at the scope where the role was assigned and try again. A quick way to open Access control (IAM) at the correct scope is to look at the Scope column and click the link next to (Inherited).
For revoking user access on a Storage account when accessing through Storage SAS and access keys
You can configure SAS expiration policy however, you may have to regenerate access keys of the storage account first and then configure a SAS expiration policy mentioned in the below link.
Hope this helps!
