The ones in your first link will not work, they are just a tiny bit too wide. I bought a pack of those, and a pack of ceramic ones of the same size and they don't fit into the tip. I've been meaning to see if I can chuck them into a dremel and sand just enough to make them fit, though.

Edit: I take that back...I just checked and these are the ones I ordered (and they are actually just a little too loose in both the 2020 M tip and the 2019 Titanium tip).

Interestingly enough, these are the ceramic ones I bought. they have the same size specified, but they are a tiny bit too wide and won't slide into the tip.
