Hi,
Thank you for posting in Microsoft Q&A forum.
Intune assignment of the new store app is the best option in my mind for your scenario. Being a store app, it's hard to speed up the process in any other supported way.
Per my experience, the best and easiest way to distribute the Company Portal when using co-management is to ensure you've moved the App workload slider to Intune (this doesn't change ConfigMgr's ability to deploy software in any way) and use the new Microsoft store app in Intune.
Refer to: Add and assign the Windows Company Portal app for Intune managed devices
Thanks for your time. Have a nice day!
Best regards,
Simon
