This custom function RECOGNIZES AND TRIMS SWISS TELEPHONE NUMBERS into an easy-to-read format

- Any phone number with swiss prefix will be returned formatted in 3 groups. E. g.: 079 888 77 66, 0800 88 77 66, 062 888 77 66
- Any other numbers will be returned as entered
- Any non-digit character will be removed

Create a backup-field with an exit script trigger, that stores the original number!
