I, John, am the one who heard and saw all these things. And when I heard and saw them, I fell down to worship at the feet of the angel who showed them to me. 9 But he said, “No, don’t worship me. I am a servant of God, just like you and your brothers the prophets, as well as all who obey what is written in this book. Worship only God!”
Revelation 22:8,9 (NLT) BibleGateway
John becomes of the 24 Elders, how could he bow to an angel and need to be rebuked? Even he is still learning, he’s ‘not there yet.’ Revelation takes place in the future, John seeing it unfold in his life on earth.
