There actually wasn't a predrill size in the instructions if doing it in drywall>stud. The ones for brick/concrete gave a predrill size that included wall plugs (8mm/0.314 inch drill bit)

I always pre drill into stud if it’s any type of load bearing like this is. Just start from a small bit and increase size until youre approaching but still smaller diameter than the target screw. And you can use a regular (non power) screwdriver for the last few turns if needed. Good luck!
