Use Azure Policy at scale at an MSP

Hi there,

I am starting to use Azure Lighthouse and Policy at a MSP. I want to use Azure Policy to manage all the delegated customer subscriptions. It seems that there is no built-in option to just push initiatives and policies to subscriptions in different tenants, and to monitor the compliance state of each policy afterwards.
In the article https://zcusa.951200.xyz/en-us/azure/lighthouse/how-to/policy-at-scale is mentioned that through Powershell you can deploy a policy to multiple subscriptions, but that you cannot view compliance details.

What would be the best way to achieve both deploying and monitor compliance within a MSP environment?
