So 3A switched fuse spur is required.
I’d prefer to see the spur taken off your power circuit as it’s in the kitchen but you could take it from the lighting similar to a bathroom extract fan.
If you’re going to attempt this yourself and you...
Needs to go into a fused switch spur
Do not take the power from the cooker socket and if that’s your thoughts, maybe you should leave it to a professional.
What is the KW of your extractor?
