3. In the popup select the ‘Access Local Extensions’ on the bottom right.
4. Every Tableau extension has a manifest file (`.trex`) that describes the extension and identifies the location of the web application.
5. If prompted, allow or deny the dashboard extension access to the data in the workbook.\
   All extensions have access to the summary data in the dashboard (this is the visible data). Some dashboard extensions might request access to full data, which includes the underlying data in the view, and information about the data sources, such as the names of the connection, fields, and tables. For more information, [Data security and dashboard extensions](https://onlinehelp.tableau.com/v2018.2/pro/desktop/en-us/dashboard_extensions.html#Data).If access is granted, the dashboard extension appears and runs through the initialization sequence. Follow any on screen instructions for configuring and running the extension with your dashboard.

1. Select the extension zone in the dashboard, and click Remove from Dashboard from the drop-down menu in the upper-right corner.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.infotopics.com/deployment-and-licensing/tableau-platform-support/tableau-desktop-support/adding-an-extension-to-a-dashboard.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
