Help Samsung notification 'Google Drive' share request from

[Android Question]

I was swiping through my notifications on my lockscreen (Android 6.0.1; Samsung s6e) and a 'Google Drive' notification had popped up. It was VERY sketchy from something like 'nCdcweEd@asdEdc.com' with a very obvious "Dear Sir, We are a Chinese company selling [...]". So my immediate reaction is to close it; however, holding down the specific notification, seems as though I pressed it and it immediately pops up to a .jpg of some sort of mechanical equipment.

So to leave the image I press my back button. But now I'm back in my homescreen: no email evidence in my gmail accts, checked all my 'recent' docs on google drive – nothing... Also check my phone's recent downloads and nothing, but I'm just very weirded out.

I went and changed all my gmail passwords.. is there any way to trace what's going on? Has anyone experienced similar?
