you could say the same thing about christ and his apostles. was he "not hiding it" when performing miracles in front of others? he could be looked upon as arrogant in cases like that. but as it's well known, in many of those cases, he specifically told the witnesses not to advertise him as a healer and miracle worker. as it is written:
when you pray, do not be like the hypocrites and show off, but rather go into the inner rooms and pray to him, and he who is in secret will reward you
