Sterilizing baby Brezza Bottles?

So I just bought some baby Brezza bottles I got for a good deal, but after I bought them I was reading on their website and it says the nipples aren’t microwave sterilizer safe which I just find so weird for baby bottles nowadays, but whatever... anyways I already have a microwave sterilizer from my first so I’m really not wanting to buy a different type. So my question is has anyone put the baby Brezza Bottles and nipples in a microwave sterilizer and what was the result? Lol. Or has anyone sterilized them using the old school boiling water in a pot option and should take be okay instead? I’m worried that if they aren’t safe for the microwave that they’ll melt in the pot of boiling water..... any help would be great!
