Adding Apps from Catalog or Store using CSOM API
As provisioning process, we would love to either add apps from app catalog or store directly using CSOM APIs. This should include the 'I Trust it' model as well. This will help in automating the entire site/sub-site provisioning and making sure apps are available after site is created.
Thanks for your feedback! We’re reviewing your suggestion. Initial thinking is to provide capability to publish SPFx solutions and add-ins from app catalog to sites. Having same level of automation for the store process is much more complicated challenge, due possible licensing models with the store add-ins.

Is there a PowerShell way to do this from the store?
