Googling around, I find a bunch of different recommendations on what to do with a new chain, ie, install it as is with factory grease, degrease it a little bit, degrease it completely.
Going to the source
https://www.kmcchain.eu/service/how-...at-a-new-chain
it says
A new chain usually feels sticky at first. These are residues of the high-performance grease used during assembly. Remove this grease with a thin-bodied oil or cleaner (no aggressive grease solvents!), lightly oil the rollers and remove excess oil with a cloth. After that you're ready to roll.
We recommend never to degrease the chain completely.
Stupid question: what is a thin-bodied oil?
