iOS 15 hasn't been signed in some time. If your tag line is accurate and you do own iPhone X, you can update to it's most current version, iOS 16.7.6.
Here is a link which explains how to update an iPhone --> Update your iPhone or iPad - Apple Support
Since you have skipped a number of updates on your iPhone, you may find updating it using your computer with iTunes (Windows) or Finder (Mac) may be necessary --> Update your iPhone, iPad, or iPod touch with iTunes - Apple Support
