Why did the angel tell John when he fell down to worship him to refrain and to only worship God?

And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things. Then saith he unto me, See thou do it not: for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God.
Revelation 22:8-9



Why did Jesus not correct Thomas below when he called Him his “Lord and God”? As the angel corrected John not to worship him, wouldn’t Jesus have done the same if He were not God?

Thomas answered him, “My Lord and my God!”

Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen, and yet have believed.

John 20:28-29
