How can I call an extrinsic on a palette using the polkadot-js-api CLI tool? I don't see much documentation on the tool nor does the --help provide much detail. Could I use this tool for this purpose? I would like to call an extrinsic that takes a local file as input using the @ parameter and passes the contents to a custom extrinsic on a custom palette. If not, what are some other tools I could use rather than coding my own?
