    set_purpose ("some claims").

    Let _ = anchor_lang :::: create_pda (Create_pda) .signers ();

    // Get the PDA account ID

    Let pda_account_id = get_pda_account_id ("some_mnemonic");

    // Close the PDA account

    Account_state.close_pda_account (PDA_Account_ID, "Causted Conclosing" .to_string ()).

    // update them

    Adudl_TeKen_Account (
