Adjust tablenotes to rescaled table

I have a wide table (more than in the MWE if I start putting numbers in there) and use resizebox to fit it. However, in the threeparttable environment it does not let me put the footnotes inside the rescaled box, which is why they exceed the width of the table. Any suggestions how to approach this?
