Path to crx not working

I tried to add an extension using the path
Run Keyword If '{EXECUTE}' == 'localChrome' Call Method {chrome_options} add_extension C:\Users\H80606\Desktop\api-automating-framework\robot\Resources\Proxy-Auto-Auth_v2.0.crx
but I always get Calling method ‘add_extension’ failed: OSError: Path to the extension doesn’t exist

Can anyone help me please

Backslashes in Python must be escaped, so you need to write \\ for each one. Maybe your command accepts forward slashes.
