In Matthew 28, what did the angel do after rolling away the stone from the tomb?

Answer: Sat on it

After a great earthquake, the angel rolled back the stone and sat on it; the guards shook and became like dead men.

“Suddenly there was a great earthquake, for an angel of the Lord descended from heaven, rolled away the stone, and sat on it. His appearance was like lightning, and his clothes were white as snow. The guards trembled in fear of him and became like dead men.”— Matthew 28:2-4 (BSB)
