How to keep updating a path folder for mapping file using PowerShell?

I have some folder, inside those folder has a file call it SSID_LST. Inside the SSID_LST file there is a string. I want to match the SSID_LST with $SSIDUnit. If it is match, It will return the folder path. If its not match, it will show the GUI and do looping to check which SSID_LST match with the $SSIDUnit. In this code, I can get the folder which match with $SSIDUnit. But once it is not matched and show GUI for doing check match $SSIDUnit, and then I drop a new folder contain of SSID_LST and inside the SSID_LST match with $SSIDUnit, it does not check the SSID_LST in new folder that I drop. It only checking the old folder. Its like how to update the $Path to check the existing folder to find SSID_LST file.

I have to do updating in this part, if there is a new folder drop to $JobFolder, it will include the new folder for checking the SSID_LST file.

$Path = Get-ChildItem "$JobFolder\*\$SSIDName\"
Write-Output "Path SSID : $Path"

Anyone has an idea about it? I refer to this answer https://stackoverflow.com/a/57524097/11099245
