Hello Issah,
Welcome to Apple Support Communities.
From what I understand, you iPhone XS Max was in water for about 1 minute and now the iPhone is turning off, no vibration and lines appear on the display, correct? I'm here to help you take a look in to that!
Here is an article to read over about water resistants with the iPhone XS Max:

With the events happening with your iPhone, I would encourage a backup to iCloud or iTunes:

Based on your description, I would encourage you to reach out to Apple Support directly. They will be able to provide you with additional information and review different options with you:
