Revelation Chapter 4, Verse 10 (GWD)

^4:10 the 24 leaders bow in front of the one who sits on the throne and worship the one who lives forever and ever. They place their crowns in front of the throne and say,

the 24 leaders

bow in front of the ONE who sits on the THRONE and
worship the ONE who lives FOREVER AND EVER.
They place their crowns in front of the throne and say,

When the four living creatures give GLORY, HONOR, and THANKS in verse 9, the ripple effect upon the 24 leaders is to cause them to do the three actions above.

"bow in front of" means total submission as a servant before the Master.
"worship the ONE" means to give all praise to the Forever God.
"they place their crowns in front of the throne" means we/they recognize that even what we/they have been rewarded rightly belongs back with the Lord because of his GREAT WORK!

This GREAT WORK is a recognition of Christ's work IN US of regeneration; 1 John 3:2 -- we shall be like Him, He is not like us (physically sinful) today.

This GREAT WORK is a recognition of Christ's work THROUGH US of service; Romans 1:18-19 -- God is made evident in us. "Let the beauty of Jesus be seen in me!"

This GREAT WORK is a recognition of Christ's work FOR US of keeping, cleansing, protecting, and perfecting; Philippians 3:20-21 -- transforming our body.

The CROWN I receive is because Jesus Christ bears much fruit through me. So I really didn't get and don't deserve my crown anyway (John 15:4-5-8).
