InTune Company Portal Media Player Options

Good day!

Recently deployed MDM using InTune, Authenticator and Company portal. We did add a host of business applications but are now running up against attachment handling from Outlook for media files. The message is: No available apps. There are no apps currently configured on this device that your organization allows to open this content. Please ensure you are signed in with your work or school account to your managed apps or contact your IT helpdesk.

It appears I will need to add a managed application to the portal and was wondering what others were using and why. I am looking at VLC because it is cross platform, free, no adds and open source and plays a variety of media. Would this be a good option or are there better options?

Thanks in advance for any insight offered!
