They did. Here you go, video showing some of them, including Bissouma and the number 34 at the time calling for a free kick for them and the ref being badgered by Gross while VAR looked at it.

But even if they didn't it wouldn't necessarily mean anything, there have been times, like the Aurier penalty that Mane bought for Liverpool where players don't complain much, but should (even most of our supporters were blaming Aurier) and wouldn't change the fact that whatever Lallana did, Kane made absolutely no attempt to go for the ball, just looked to see where Lallana was and bought a pen. I have no problem with it, even Kane admits in that interview it's a 50/50 decision.
You don't judge what happens by reaction of others, you judge it by you know...what actually happened.
I don't think it was an outrageous bit of cheating by Kane, but he won that pen with a bit of smart thinking, but I'm not alone in thinking most times that kind of play would see a free kick go the other way.
And my initial point stands, without that pen we don't win that game, a game which neither side created much and they had 57% of the ball.
