@NipunaRanasinghe do we need to add library-templates/generated-connector-template/files/LICENSE ? AFAIK this would be added during the initial repo creation process.

Yeah thats the case for our repos. But incase we need to use this workflow for the external repos (especially during the connector externalization event), better to make the license a part of the template to avoid any copyright issues in the future IMO.

So the PRs will change the license only if the target repo doesn't have it, and there will be no changes otherwise. wdyt?

LGTM shall we add the standard workflows for the repo?

Yes those should also be a part of the templates. Missed to commit them. Thanks for pointing that out!
