In Editor or Admin group, User can select environment in left bottom menu.
But In Viewer group, environment menu is not visible.
How do I enable enviroment select menu in viewer group?
Hi @joshua1 ! Thanks for asking - can you confirm whether you're using Retool on Cloud or Self-hosted? Allowing Viewers to toggle environments is possible to enable via a feature flag on our side. If you can write in to Retool Support via the in-app chat or by emailing support@retool.com and let us know the name of your Retool org, we can help with this.
I am using Retool on cloud.
Where is the flag that you mentioned to enable toggle environment?
Can you give me a guide?
Hi @joshua1,
Enabling feature flags (features of Retool that are a work in progress/beta) is something we would need to set for your account on our side. If this is something you would like to have available for your organization, please contact us through the in-app chat or by emailing us at support@retool.com with our organization/subdomain name and we should be able to set that up for you. Hope that helps! 
Kenny
