"My Inbox": how to enable full width within Fiori launchpad?

Question

I'm extending My Inbox standard Fiori app so that it fits the whole screen like the image bellow.

Hence, I've added in the manifest.json of my My Inbox extension (and the apps used in My Inbox, just in case) this line:

{
  "sap.ui": {
    "fullWidth": true
  }
}

When the app is launched, it begins to be full screen, but then it comes back to the standard presentation.

Can anybody help me please?

I manage to find a solution: the fullwidth is actually redefine in the Component.js of My Inbox standard app. So I added these lines in the My Inbox extension project:

manifest.json

{
  "sap.ui": {
    "fullWidth": true
  }
}

Component.js

this.cross.fnd.fiori.inbox.Component.extend("cross.fnd.fiori.inbox.CA_FIORI_INBOX_EXTENSION.Component", {
    metadata: {
        manifest: "json"
    },
    
    /* Override code : begin ----------------------------------------------------- */
    //function to handle the width of the application. It is called by FLP when app is active.
    active: function () {
            sap.ushell.services.AppConfiguration.setApplicationFullWidth(true);
    }
    /* Override code : end ----------------------------------------------------- */
});
