Securing integrated dishwasher underneath stone worktop

I need to secure an integrated dishwasher to the underside of a stone worktop to prevent it tipping over when opened.

I found these online which will do job but they are only available in the US. Low profile Granite Grabbers https://www.kraydad.com/granite-grabbers-dishwasher-mounting-brackets/

Securing from the side of using a piece of wood on the top are not options. Does anyone know of something similar which is readily available in the UK?
