How to close Activity window?

[Ytzen Lont]

Hello, in the new layout of Trello cards (as of today, May 21, with new buttons on the top of the card, which is an improvement) on the right side of the card there's a permanent window open (in Dutch: "Opmerkingen en activiteit", which translates as "Notes and activity"). This is very distracting, disturbing and annoying; I really don't want to see this. How can I close this window? Thanks for any reply and/or bug fixes.

You can collapse the card comments section by clicking on the rightmost button on the bottom island below the card

Thanks. Wonderful, this works. I didn't expect the button there, had been looking all over the card left and right, up and down, but hadn'tlooked at the 'bottom island'. Thanks for the info.
