Configure Popup Attributes Programmatically with ArcGIS API for Python

[NathanielEvatt]

I am hoping to run a script that can hide certain fields from an ArcGIS Online web map.  In ArcGIS Online, I would accomplish this by opening a webmap, clicking the three dots of the layer I was interested in, selecting "configure pop-up" then selecting "Configure Attribute".  Finally from there I can edit the display options in the GUI shown below.  

Is this something that is currently configurable from the ArcGIS API for Python?

I'm still a newbie to all this stuff, is there a reason this command doesn't always work?

if I edit the visualization for my pop ups I can get to the data using the command.  If I don't I can't pull back any data.

# Get the Item itself
    flc_itm = gis.content.get(fl_itmid)
