compatibility front derailleur / crankset ( convert 1x to 2x )

I want to convert my Ibis hakka mx 1x grx to 2x grx

https://www.ibiscycles.com/bikes/hakka-mx

Cranks Praxis Zayante Carbon S 30mm spindle, 40t Alloy Ring

Bottom Bracket Praxis M30 - T47
Rear Derailleur Shimano GRX RX812 Shadow Plus
Shift Levers Shimano GRX R810
Cassette Shimano XT 11-46



I purchased the left Shimano GRX ST-RX810 Hydraulic Brake Lever. I have 11-40T cassette also. I don't think the 11-46 will work with 2x setup.

I can purchase 2x chainring for the Praxis Zayant carbon crankset that's on my bike. The praxis website says it's

not compatible with 2x grx front derailleur.
https://praxiscycles.com/product/zayante-carbon/
CHAINLINE 2X = 44.5mm ROAD | NOT compatible with Shimano GRX front derailleurs

1X = 45.5mm ROAD


Can I just buy this?
Shimano Dura-Ace Front Derailleur Braze-On Adaptor

Shimano GRX FD-RX810 11-Speed Front Derailleur

https://www.biketiresdirect.com/prod...ont-derailleur

or do I need to buy this to work the praxis crankset ?
Shimano Ultegra FD-R8000-F Braze On Front Derailleur

https://www.biketiresdirect.com/prod...ont-derailleur

or should I just buy

Shimano GRX 810 2x11 Crankset and buy a new bottom bracket for the T47 so I will have matching grx front and rear Derailleur

I have seen non shimano cranksets work with grx Front Derailleur.
My 2021 Giant Revolt comes with
Crankset Praxis Albe 2D, 32/48
https://www.giant-bicycles.com/us/revolt-advanced-2

yet Praxis says that crankset
https://praxiscycles.com/product/alba/
CHAINLINE 2X = 44.5mm ROAD | NOT compatible with Shimano GRX front derailleurs


So, I don't know what to believe any more.
