Splash Screen After Login in native mobile app

Hi Team, After logging in, our native app shows a white screen for a few minutes before displaying the dashboard. We need to show a splash screen during this time. Currently, the app shows a splash screen when it launches, then opens the login page. How can we add a splash screen between the login and dashboard? Thanks in advance.

What happens during that time? I assume it's synchronizing a lot of data. AFAIK you do not have visual control (like show XYZ) over this process.
