Curtain track installation

Hello, I would like to install a curtain track on the ceiling to divide a room. Please see the red line for the position of the track on the pictures. I can buy the track myself, or please let me know if you have a recommendation or would like to provide one. The length is 288cm. I only need the curtain track to be installed, as I have the curtain and can install the curtain myself. Thank you!
