That is, we "know" that if we ignore later verses and the witnesses we don't like. Otherwise we "know" no such thing.
There is NO suggestion whatsoever, "not even of any kind" in the text. It is an assumption, that the the instruction in the text you cite over and over again, as though repetition were a kind of proof, and discussion a matter more of endurance than of reason, has to do with the general ministry of the 12. And there are texts -- I quoted one -- which can be reasonably understood as instructions, after the resurrection, to go into all the world.
Do the words of our Lord and Saviour qualify as text? [John 21:15-17] pretty much bears this out.
