I am not sure what you are asking is possible in the conventional sense.
XMP files need to be stored side by side with the original raw file. If they are when they are imported, Lightroom should recognize and pair them together.
As a test, try this:
- Locate one of your original files from those supplied by support.
- Locate the .xmp file with the same name.
- Put them together in a folder.
- Import that raw file
Does the file come in with edits?
If so, repeat for the remainder of the photos.
