You don’t need to rebuild the extension, installing it from pip or conda is enough. The configuration is detailed at [JupyterLab App Launcher Documentation — JupyterLab App Launcher](https://jupyter-app-launcher.readthedocs.io/en/latest/)

@trungleduc Glad to recieve this reply, thanks. I already tried this and create a path named jupyter\_app\_launcher under the directory of jupyter data path, then created a jp\_app\_launcher\_my\_extension.yaml , customized my conten into this yaml file and it displays ok. But what confuses me is why neither compilation nor direct installation can display the samples contained in code.([jupyter\_app\_launcher/samples at v0.1.7 · trungleduc/jupyter\_app\_launcher · GitHub](https://github.com/trungleduc/jupyter_app_launcher/tree/v0.1.7/samples)). In the installation or compilation progress , does it copy this yaml file to data path?

No it does not. You need to create the config yourself

@trungleduc Does there have any methods to remove the default jupyter launcher content of main area , only retain customized content？

What do you think about adding functionality similar to `jupyter-app-launcher` into JupyterLab core say for 4.2. or 4.3? It seems like customization of the laucher seems like a common use case. In lab we could have a just a list of settings for it.

it would be great! I think a stripped-down version of this extension can go to the core, which allows users to create launcher icons to execute JupyterLab commands.

Is it possible to launch a (Voila) notebook as a different user? We have a jupyter hub running on a server and we want a notebook to appear on the launcher, but when it is launched it has different permissions/privileges than the user who has logged in and is running the notebook. Hope this is making sense.
