I think the codeowner should have contributed several issues about this component, and get sponsor from existing codeowners.

@zdaratom
Do you have contributed for datasetexporter? Do you get the sponsor from existing owners?

[zdaratom-s1]

Yes I do have sponsor from @martin-majlis-s1, the reason why I created this PR was to Authorise EasyCLA - that was the suggested approach in docs - create PR in order to get authorization in EasyCLA
