make apps visible to entire organization ?

Hi

Do you mean:
An app is visible in app market, everyone of the organization can see it but can’t get it unless the app creator give access to them?
Or, the entire organization can get this app but only read and can’t edit it, unless the app creator give access to them so they can edit it?
For condition 1, it is not possible because if a user has no access to getting an app he will not see it in market place.
For condition 2,
set the app workspace in which you create an app and publish it as “members can only view Power BI context”, then give access to entire organization while publishing an app, the user can get the app but only read it.
If someone ask for a permission to edit it, you can add him as a member of the app workspace and set Privacy of this app workspace as “members can edit Power BI context”.
