If you lost the address, you can always pull up PolkadotJs Apps and check the chain state for the contract address.
┌ Pop CLI : Calling a contract
│
◐ Calling the contract...
⚙ Result: Ok(false)
│
▲ Your call has not been executed.
│
▲ To submit the transaction and execute the call on chain, add -x/--execute flag to the command.
│
└ Call completed successfully!
The result here is false meaning that value in the contract storage is set to false.
Let's try flipping it. Remember to update the contract address accordingly.
