Medela sterilizing bags

So I’m a ftm and have no clue how this breastfeeding and pumping thing goes. I have a spectra breast pump and nuk natural bottles along with the kindee twist pouches. Am I able to use the medela sterilizing microwave bags on the spectra pump supplies and nuk bottles or do you sterilize them a different way?
