It's not clear exactly what verse 12 is saying here. The word "with" seems to suggest that the "signs and wonders and mighty works" are something distinct from and in addition to "the signs of a true apostle", but exactly what those signs are, much like the origin of the quote in Acts 20:35, is information not found in the Bible.
With regards to the specific question, Latter-Day Saints do not demand miracles of apostles as a validation of their authority, and typically consider that to do so would run afoul of Matthew 16:4.
