Trying to sync calendar from iOS to Outlook

My daughter's soccer team uses an app, TeamSnap, and it allows us to sync the calendar to our phone. It created a separate iOS calendar when I subscribed to it, which is nice, and it will update when the coach/manager changes anything within the app.

I'm trying to sync/copy it to our family shared Outlook calendar. I can manually add each one to the Outlook, but it won't pick up any changes. The wife is finally trying to get organized and keep a digital calendar, instead of her old method of a planner, so I'm all in on trying to figure out if there is a way to copy these over while picking up any changes that happen as well.
