Battery replacement for Omnibook Ultra Flip 14 - PLEASE HELP

HP says they are in back order.

My understanding is that the main part is P07278-001, but seemingly there are others(?): HSTNN-WB0I, N76519-1E1, N76519-171, N76519-CF1, N76918-005, , RS06XL, RS06064XL, TPN-IB1D.

I don’t get how that works, but I’ve got a torx set and can repair myself, so of the following options, which would you buy? I’m in Canada. Meanwhile, if i’ve missed a good place to find one of these, please let me know:
