Limit switch issue with a longer button

I had to order a new limit switch for my z axis since my original got crushed. The issue I’m running into is the new switch seems to have a longer button. So, when homing, it moves into the button then tries to pull back to disengage but the travel doesn’t seem far enough back and results in an error.

I test it by lowering the z so I could manually engage the switch and reengage it. It worked and continued to home the x and y axis.

The question is, can the homing sequence be modified so when pulling off the switch to disengage the button, how can the distance be increased in order to disengage the new switch?

Grbl setting $27 sets the pullback distance in mm.
