About the compound_id of the accounts table described in the documentation

What value should I set for the compound_id column? If anyone knows, please let me know.
I don't know what it is used for. 🙏

The compound_id is just a hash ganerated with node crypto module and it ensures that there is only one instance of an OAuth account in a way that works across different databases.

This is how it works with the default adapter:

const compoundId = createHash("sha256")
  .update(`${providerId}:${providerAccountId}`)
  .digest("hex")
