Although there’s a official still of Ronan in the same room as the Starforce, in the final Captain Marvel cut, he never had any direct face time with them.
Instead, he communicated with the team over hologram, first blaming Yon-Rogg for their failure on Torfa and then arriving to Earth after Yon-Rogg contacted him about eliminating Talos and the other Skrulls.
Still a dutiful servant of the Kree empire at this stage of his life, Yon-Rogg ordered that Earth be bombed, but the fully-powered Carol Danvers destroyed the warheads and one of his ships, prompting him to order a retreat and declare that he would return to capture Carol and use her as a weapon.
As for Ronan, we find out why he’s called the Accuser: because he was part of the of the same-named division of the Kree military, which would see him ordering warheads to be dropped on planets to wipe out the enemy Skrulls.
