ApplyTenantTemplate does not provide ability to set Group Owner

I try to apply a new Tenant Template / ProvisioningHierarchy for a TeamSite, which creates a Group and then based on that Group a new Teams Team should be created. The Team itself can't be created right now, because the Group does not have an Owner.

The Owners Property of TeamSiteCollectionCreationInformation is currently not set through ObjectHierarchySequenceSites for TeamSiteCollection. Meaning, it's currently not possible to set the Owner for Team Sites throught the Template - causing all Teams deployments to fail/timeout. (In the retry, an exception is catched, but expected because Group might not be synced yet - the actual error is swallowed)

var provider = new XMLFileSystemTemplateProvider("./templates", string.Empty); var hierarchy = provider.GetHierarchy("SampleTemplate.xml"); tenant.ApplyTenantTemplate(hierarchy, "SAMPLE-SEQUENCE");

SampleTemplate.txt

Would it be possible to provide the Owner thorugh the Template for TeamSites as well?

Start in src/lib/PnP.Framework/Provisioning/ObjectHandlers/ObjectHierarchySequenceSites.cs around line 273, where TeamSiteCollectionCreationInformation is populated, and review SampleTemplate.txt for the TeamSite owner data. Make the template's owner value reach the Owners property for TeamSite and verify that applying the hierarchy can create the Teams Team successfully.
