Cancel transaction ASAP - HELP

I sent my funds to an address generated by Helix Lite before realizing it was a scam. No confirmations yet, can someone let me know how I can cancel this asap?! Tips and tricks perhaps?

Bitcoin transactions are irreversible, but if for some reason it wasn’t properly broadcasted, you should be fine just shutting down Bisq and restoring from most recent backup or seed words (if you have no open trades).
