Why performUpkeep() and fulfillRandonWords() are not shown on Etherscan under 'Transactions'?

Hi all,

I'm not able to connect some dots here.

1). performUpkeep() updates the value of a state variable - s_raffleState = RaffleState.CALCULATING; and it runs on-chain.

2). Similarly, fulfillRandomWords() resets our state variables:

s_recentWinner = recentWinner;
s_raffleState = RaffleState.OPEN;                                  
s_players = new address payable[](0);
s_lastTimeStamp = block.timestamp;

That means, these 2 are changing the state of Blockchain. Is this correct?

If not, why?

Is yes, then why do we not see these functions getting called on Rinkeby Etherscan unlike we see Enter Raffle everytime?

Seems like I'm missing something really obvious here but can't spot it.

Sorry, should have waited a couple of more seconds through the course where Patrick explained exactly this - 'Internal transactions'.
