Close pyth accs manually [Solana - svm]

Is there a way to get all the accounts created with a specific signer that have not been closed?
How to close them manually?

Same questions apply both for addPostPriceUpdates and addUpdatePriceFee.

Since the (aprox) resulting sequence of the builder is

• acc(s) creation Tx
• Write Txs
• [Consumer Ix + Close accs Ix] Tx

during our development phase, we didn’t execute many close instructions due to failures on our consumer ix, thus failing altogether and leaving the rent unclaimed.

My intention is to fetch all those accs and close them now.

Thanks for the help!
