New to tethered shooting in LrC - A couple of questions

[Alan9940]

I just setup my Canon 5D Mark II for tethered shooting on my 2015 MacBook Pro. Works great, but I have a couple of questions:

1. Is a histogram available when shooting tethered to ensure I'm not clipping, especially highlights?

2. When "Live" is active, is it possible to zoom in on this window to ensure accurate focusing when doing manual focus?

I was playing around with tethered capture in Capture One Pro, too, and it does everything I need, but... Sadly, Negative Lab Pro is only available for LrC and I need this app for conversion of digital scans.

Thank you for any help provided.
