Does the 2.8 70 to 200 RF lens work with the 2XRF extender?

Depends.  With which camera?  Refer to your User Guide.  Search for “Lens Groups”.

EOS RP looking to buy the RF 2.8 70 - 200 but looking to extend for wild life shooting

Greetings,

The RF 70-200 f2.8 or f4 is not compatible with the 1.4 or 2.0x extenders.

Your current choices would be:

RF 100-300mm f/2.8 L IS USM - TC's can be used with full focal length 100-300
RF100-400mm F5.6-8 IS USM - TC's can be used with full focal length 100-400
RF100-500mm F4.5-7.1 L IS USM - TC's can be used 300-500mm only
RF400mm F2.8 L IS USM
RF600mm F4 L IS USM
RF600mm F11 IS STM
RF800 F5.6 L IS USM
RF800mm F11 IS STM
RF1200mm F8 L IS USM

Note, its rumored Canon is developing a new 70-200 internal focus zoom which (might) mean compatibility.  It is a rumor.  It has not been announced, and some have also speculated it might include a built in TC.  This all speculative.  This is nothing more than a rumor.  I want to be sure you understand and don't delay buying a great lens based on speculation. 

I shot this last month with a RF 70-200 f2.8.  I was about 100ft away.  Note the image is cropped.

 For wildlife photography at greater distances, I would consider the RF100-400 or RF 100-500, and consider adding a TC only if one of these did not provide the reach you need.  Either would be a great mate for your RP.
