Since His ascension, has Jesus been seated on His throne or actively engaged in other roles?

Acts 1:9–11 records Jesus’ ascension into heaven. Hebrews 1:3 and other passages state that He "sat down at the right hand of the Majesty on high." Yet other verses, such as Romans 8:34 and Hebrews 7:25, describe Him as interceding for believers. Revelation 3:21 also speaks of Him sharing His Father’s throne. According to Christian theology, since His ascension, has Jesus been permanently seated on His throne, or is this meant to describe His authority while He remains actively engaged in roles such as interceding, reigning, and preparing for His return? I’m seeking an explanation based on Scripture and Christian doctrine about what Jesus has been doing since He ascended to the Father.
