How to cancel a tournament ?

Hi, I've created a tournament, but forgot to put a name
lichess.org/swiss/xRK8S3L7

Lichess game it a name : Gurvich

I'd like to change the name to : Samedi 27 juin 9h00 am

Or cancel it, How would I do that ?

Thanks

You just press the settings in the top left and there will be some options there

There is a blue gear on the upper left side if you go to the tournament page. Click that and you can change the settings.

Nice Thanks !
