Interpolate frames to get show motion ?

Hi and sorry for noob question.

I have a sequence of rendered image files. The frame rate was 24 and total number of frames 120.

My question is, whether it is possible to extend the total number of frames to 240 and let Fusion create / interpolate the inbetween frames? In the end the clip should look like a slow motion.

Thanks in advance for tips.

EDIT:
I found TimeSpeed tool. Is that the right one to use?

Use Optical Flow to generate the needed channels for TimeSpeed to process to stretch the footage, then average the frames together.

Thanks,

will do so.
