How do I change the default splash screen?

I made an app and downloaded it to check how it works. The problem is The app starts running with thunkable screen which says made with thunkable. How to change this?

Splash screen change only if you have a Pro member account.
when you are pro member splash screen takes your app icon

If you are a PRO member then you need to load an image for the app icon which is found in project settings panel.
