I dont see them ever accepting the drug ever, but I would see them just simply recognize the mutant state and thus act accordingly and in continuity (aka spying on them to see if they lose a threat to Wakanda in the future)
the only other way I would see them accept the bribe would be if T'Challa had a reason and plan for doing so, but that's Priest and Hudlin panther that would do that. The current writer i honestly would not trust having T'Challa or Wakanda react to it, which then means it would fall on Hickman to decide. Which is worrying knowing Hickman at times
