Bevel a Plane

Is there a way to curve the corner with a bevel? I’ve tried but it will not let me.

Bevel vertices = Shift + Cmd + B
I think you tried only bevel edges

hello, hard to say with so few informations, once you’ve Ctrl B, take a look at the Operator box (bottom left of your 3D view) and check the options

Thanks guys, it works now
