    spl-token authorize [FLAGS] [OPTIONS] <TOKEN_ADDRESS> <AUTHORITY_TYPE> <AUTHORITY_ADDRESS>

FLAGS:
        --disable                     Disable mint, freeze, or close functionality by setting authority to None.
        --dump-transaction-message    Display the base64 encoded binary transaction message in sign-only mode
    -h, --help                        Prints help information
        --sign-only                   Sign the transaction offline
    -V, --version                     Prints version information

OPTIONS:
        --authority <KEYPAIR>
            Specify the current authority keypair. Defaults to the client keypair.

        --blockhash <BLOCKHASH>                           Use the supplied blockhash
        --with-compute-unit-limit <COMPUTE-UNIT-LIMIT>    Set compute unit limit for transaction, in compute units.
        --with-compute-unit-price <COMPUTE-UNIT-PRICE>
            Set compute unit price for transaction, in increments of 0.000001 lamports per compute unit.
