Okay, so update on my bluetooth pairing issue with the app. I was able to get the IGLA into HID mode, however that mode doesn't use the iPhone app, it just perpetually has you connected to the IGLA and leaves the IGLA in a mode where it's discoverable to iPhones close enough to the truck. I could not get the app to pick up my connection to the IGLA unit either.
So, while it does work and allowed the truck to start without entering my passcode, it's not really the solution I was looking for. Technically you could just toggle on/off your bluetooth in the iPhone settings every time you walk up, but I don't want people knowing there's an IGLA alarm somewhere close and even trying to connect to it. Let alone who knows how much parasitic battery draw that may induce?
I am more than comfortable just using the passcode every time I get in to the truck. In fact, I reached out to S&A Specialist out of Chicago who I found on youtube and they told me they highly recommend against using the phone and even the keyfobs just for security purposes. The passcode according to them is the most secure way to use the system which makes sense as no one can steal the passcode (not yet anyways until Elon's neural link company takes off

). I'll likely only use the keyfob for when I take the truck in to service by just leaving it in the glovebox. I did just that at the ceramic place who had it overnight and they were surprised when I told them I had a security system installed.
Anyways, below is the link to the documentation IGLA sent me which shows you how to change your bluetooth pairing methods. I also experimented with the folding mirrors feature and it did not work unfortunately.
