5D Mark iV and Iphone

[Booncroft]

Can I use my iPhone as a viewfinder in video mode?

If so not sure how?
Thanks!

Hello Booncroft, 

There are no provisions to use your telephone as an external monitor when shooting video with the EOS 5D Mark IV.

I actually just found a way through the canon app

I suppose it's boorish to say this, but I find it comical to see the Mark IV and the iPhone mentioned in the same sentence.
