How to send ICP from Account Identifier to ledger Canister

Many thanks,
let me ask commands:

dfx identity use minter

export MINT_ACC=$(dfx ledger account-id)

# ledger

dfx identity use default
export LEDGER_ACC=$(dfx ledger account-id)

can Account Identifier(use NNS) to be the Ledger Canister account? Or The Ledger Canister account is only our developer to hold ICP to payment, convert to cycles…?

I’m not clear, hold u can explain it.
Thanks
