Let me show you the step-by-step approach to Publish App in Power BI with a practical example. Before we start publishing the app, let me show you the existing dashboards in my workspace. For this Publishing App in Power BI demonstration, we are using Sample Workspace.
Please click on the Sample Workspace and then go to the dashboards tab to see the list of available dashboards. As you can see from the screenshot below, currently, there is only one dashboard in this workspace.

How to Publish App in Power BI
To publish App in Power BI, please click the Publish App button in the top right corner. I suggest you refer to dashboards and Create a Workspace article to understand the Power BI workspace creation.

Clicking the Publish App button opens the following Power BI window. Under the Details section,
- Description: Please provide a valid description of this App. It is a required field, so you have to fill something here.
- Background Color: Please select the background color of this App. By default, Green is selected.

We added the description and changed the App color to red.

Under the Content tab, specify the App landing page
- Specific Content: If you select this option, then use the dropdown list to choose the dashboard
- None: There is no landing page

Let me select the New dashboard as the landing page

Under the Access tab
- Permissions: You can give access to the entire organization or a few individuals or groups.
We selected specific individuals or groups for this publish app demo and added Kishore.

Once you have completed it, please click the Finish button.
