Publish-PSResource to Azure Container Registry throws an error, when anonymousPullEnabled: true

Steps to reproduce

I was looking for a way to allow my users to download (pull) PowerShell modules from our Azure Container Registry (ACR) without requiring authentication. I found the anonymousPullEnabled property in the ACR settings and set it to $true. This allowed users to pull modules from our ACR without authentication.

However, when I try to upload new modules (while already signed in with my admin account using Connect-AzAccount), I receive the error shown in the attachment.

Is there a better approach to allow users to pull modules from our ACR anonymously? Or am I on the wrong path? Assuming that Microsoft Artifacts hosted on ACR support anonymous pulls, it seems like this should also be possible for us — but I haven’t found any guidance online how to set this up.

Expected behavior

A login prompt, or using my current Az Session.

Actual behavior

I get the error: 
Publish-PSResource: One or more errors occurred. (Error occured while starting to upload the blob location used for publishing to ContainerRegistry: System.Net.Http.HttpRequestException 'Error occured while trying to retrieve response header: Error occured while trying to retrieve response: Response status code does not indicate success: 401 (Unauthorized).')
