Hot tub bonding

[Farmfly]

Hey all, I have a question about bonding. The internal parts of a outdoor hot tub. What parts are required to be bonded? What’s the best way to do it? Always appreciate the help.

They're listed so unless in the instructions all that needs bonding is already. The ground bar extra spaces allows you to bond to metal fences amd rails and whatnot that needs bonding within 5 ft of the tub
