Does anyone know how to use Signer Keys to cast message on Farcaster using NodeJS? I only find examples using mnemonic phrase but it's not what I need. I also asked the same question in the telegram group but so far no answer to fix the error.

I followed the steps of this documentation https://warpcast.notion.site/Warpcast-API-Docs-Signer-Requests-Public-e02ef71883374d2ca8d27239a8cc35d5 and I'm able to complete the step 6. I can't understand what I need to do with the step 7.

I also read this documentation https://warpcast.notion.site/Warpcast-v2-API-Documentation-c19a9494383a4ce0bd28db6d44d99ea8#adaad686f0ad4e29b1bd455e24b55b6e and it started to talk about Custody Bearer Token and Application Bearer Tokens but I don't know how to get one using my signer keys.

@dwr.eth could you please help me with my issue?
