$ bitcoin-cli help listaddressgroupings
listaddressgroupings

Lists groups of addresses which have had their common ownership
made public by common use as inputs or as the resulting change
in past transactions

The addresses must be part of inputs of transactions or of change in existing transactions. Creating addresses are not sufficient. You can read more about it on this stackexchange thread:

As you probably know, when you make a purchase, the bitcoind or bitcoin-qt client (which both use bitcoin-core) return your change by default to a new address. Well, if decide to use that address for another transaction, you have created a chain of "connectable" transactions. If you're not careful, there are various other ways that you can create connected transactions (like always using the same receiving address). However, if you already generate a new address to receive Bitcoins, this isn't a problem.

There are already numerous programs available that have the ability to scan the blockchain and list such connected transaction chains, which are definite proof that the addresses in question are or have been in the same wallet.

listaddressgroupings is a method that allow users to have the same ability to discern which groups of their addresses are connected on the public blockchain. It allows users to use the (relatively) new coin control functionality with greater awareness of potential privacy-revealing issues.
