Need to check MS Team background file

I have deployed few backgrounds for MS teams and now i need to check whether all the background files installed successfully installed or not?
please suggest me or help me how to check, i have used the below relevance but it failed.

exists of file of folder “\AppData\Roaming\Microsoft\Teams\Backgrounds\Uploads” of folders of folders “c:\users” whose (set of (names of files of it as lowercase) contains set of (“agility mirrored.png”))

Could you please provide the exact file path you are attempting to verify? Based on your relevance, it seems you are trying to find "agility mirrored.png" under \AppData\Roaming\Microsoft\Teams\Backgrounds\Uploads within the C:\Users directory. If this assumption is correct, you can achieve this using the following relevance query:

exists folder "\AppData\Roaming\Microsoft\Teams\Backgrounds\Uploads" whose (exists file "agility mirrored.png" of it) of folders of folders "c:\users"
