what kind of license need to be used in ask data in tableau, whether its creator, viewer or explorer license?

Hi @Krishna Jeevan​ 

I did think anyone - even viewers could use Ask Data, though it'll likely require an admin or creator to set it up. "That’s right, now everyone with a Tableau license—Creators, Explorers, and now Viewers—can access both Ask Data and Explain Data" - https://www.tableau.com/blog/tableau-release-ask-data-explain-data-viewers-collections

Post back and let me know if that helps and matches your experience.
