How to use Chainlink AggregatorV3Interface with UUPSUpgradeable

Would like to use Chainlink's AggregatorV3Interface.sol with OpenZeppelin upgradable's contract under the UUPS proxy pattern.

Is there any example online to update

priceFeed = AggregatorV3Interface(0x9326BFA02ADD2366b30bacB125260Af641031331); // Kovan Testnet

on version 2 of the smart contract?

Has anyone successfully done so?

Thank you!
