Open webcal URI with Outlook

I have a webcal:// link that I wish to open with Microsoft Outlook. When I click the link, it automatically launches the default iOS Calendar. The link is a shared calendar.

I would like to provide the ability for the User to open the file with Outlook.

I found the below URI scheme (in another SO answer) to add an individual item to the Calendar, but not subscribe to a shared one.

ms-outlook://events/new?title=yourTitle

Sample Calendar file:
