Deploying Lock Screen as a slideshow in Azure AD + Intune fully cloud-based architecture

[IntuneAdmin2000]

We are trying to deploy a lock-screen slideshow to display messages to all user devices. We were able to this with group-policy previously. However, we have recently ditched all on-premises servers and moved to a fully cloud-based architecture with Azure AD and Intune to manage our corporate devices. Intune does not allow this setting, is there a workaround that we can use?

I currently don't see a way to do this through CSP as this only allows for an image (https://docs.microsoft.com/en-us/windows/client-management/mdm/personalization-csp).
Your best bet will be to configure this through Powershell

@Thijs Lecomte Can you please guide me with the Powershell scripts that I can use?

I don't have any experience with it myself. This might be of help: https://superuser.com/questions/1243643/is-there-a-way-to-get-a-windows-10-lock-screen-slide-show-wi...
