Is it possible to show a message when app downloads and updates the latest code using ionic deploy

I use the auto update method to update the app using ionic pro, The problem is when there is a slow internet connection, The app takes more time to update the app, The splash screen is shown long time.

Users think that there is a problem in the app and it hangs at the splash screen.

Is there any way to so show a message while updating the app at splash screen ?
At least the user will know that the app is being updated.

<plugin name="cordova-plugin-ionic" spec="5.3.0">
        <variable name="APP_ID" value="xxxxxx" />
        <variable name="CHANNEL_NAME" value="Production" />
        <variable name="UPDATE_METHOD" value="auto" />
        <variable name="UPDATE_API" value="" />
        <variable name="MAX_STORE" value="2" />
        <variable name="MIN_BACKGROUND_DURATION" value="30" />
