@developerkunal @ncastrocosta Would you happen to know if this is being worked on? Are PR's welcome?

@ncastrocosta Sincere apologies for a delayed response on this, but thanks for requesting this.

@joshuabaird We are actively trying to clear our backlog and add new features to the provider, but support for action's data-source is currently not being worked upon. Having said that, PRs are 100% welcomed. We'd be happy to receive your contribution.

Let me know if I could help. Please tag me for any PR review. Thank you once again!
