Playbook elastalert rules are not working after updating rules from sigma repo

[peas100]

Hi I am new to security onion playbook feature. I am trying to update the Sigma rules. As per documentation it has referred sigma rules from https://github.com/Neo23x0/sigma/tree/master/rules.
However when trying to do so-playbook-ruleupdate there are no new rules fetched. I checked playbook_bulk-update.py,
it is pulling from https://github.com/Security-Onion-Solutions/sigma.git.
Above repo is not updated since Nov 2020.

So I modified the URL. (Is this correct way?)
New plays are added, however the elastalert rule created is not matching with data (Rule is quite different than the rule being created using uncoder.io).

In playbook.py there are few backend options used while converting. Does that need update?
Could anyone let me know if there is something missing?

There is ongoing work around this feature - I will update this Discussion with more details once we have it figured out.
