We made the app and embed the whole business logic and work flows into it
this app have their own authentication no retool login is required
we published the app but it is not publicly available for the prd users
we have to make it available for the production customer fast
please let me know the feasible solution
then we have to add the custom domain too with this app only
Publishing your app and connecting it to custom domain are two different steps.
You can publish your app using the ‘Publish’ button in the top right corner. As long as the person whose going to use the app is added, they can access it. Do check which plan you’re on because there are restrictions
Hi @Adil_Rana ! Welcome to the Community forum 
Happy to hear that you have been trying out our new app builder! Since it is in beta at the moment, there are features that are not available yet, but we are actively working on adding in the future.
We have added your +1 to public app sharing, and I recommend that you also follow this thread for any new updates on this feature for the new app builder!
