Lets say i have a contract which includes a function that deploys new ERC721 contract:

function createCollection(
    uint256 _price, uint256 _maxSupply, string memory _name, string memory _symbol, 
    address _requsetFrom, string memory _uri, bytes32 salt
    ) external payable returns(address)  {
        if (msg.value < s_createFee) {
            revert CollectionCreator__InsufficientAmount();
        CollectionV2 newNft = new CollectionV2(_name,_symbol,_price,_maxSupply,_requsetFrom, _uri);
        address _contractAddress = address(newNft);
    emit NewCollection(_requsetFrom, _contractAddress);

And i returned the address of new contract, but when i want to get address of new contract in the backend it returns me the transaction:

const Collection = await ERC721Creator.createCollection(10,100,'test','tst',deployer.address,'someuri')
  await Collection.wait(1)

It returns me a ton of information about this transaction, what i must to do? thanks

According to Rohan answer i got address this way:

const Collection = await ERC721Creator.createCollection(10,100,'test','tst',deployer.address,'someuri')
  const tx = await Collection.wait(1)
  const newContractAddress = tx.events[0].args[1]

I believe all you need to do is assign your await Collection.wait(1) to a variable such as

const txReceipt = await Collection.wait(1)

Then you can console.log your address like this

console.log("Your new address:", txReceipt.events[0].args._contractAddress)

you may need to use a different events index depending on if you make any contract function calls that emit events inside them
