Write-Verbose "Elapsed Time: $(($StartTime - $EndTime).totalseconds) seconds"

Bugs:
Clear-EdgeCacheFiles doesn't exist, should be Clear-EdgeCache

Additionally the paths in this function are poorly formed and missing a "\" symbol

"C:\Users$user" should be "C:\Users\$user"

"$EdgeAppData$cachePath" should be "$EdgeAppData\$cachePath"
