if I had to create such an app, I would approach it as follows:
The challenge here is to determine whether the string found is a license plate. (by RegEx? there is also an own Regex-Flow for this)
The next challenge is that license plates look different from country to country. (France, Poland, Germany, etc.) Should the validation be done on one country only. There are online Regex tools where you can test the strings in advance: https://www.regextester.com/96875
This does not seem to be related to PCF, moving it to PowerApps forum.
