Remove google app page that got added as an extra home screen on nexus 6p

[AC Question]

I had only one home screen before but now i have got two- the Google app screen has got added some how. I tried removing it by pressing on the screen for a few seconds, expecting a trash sign would appear and then I would drag this screen and drop it in the trash. But this doesn't happen for this Google screen page, could you please suggest how to remove it? Thanks
