For pic cache function, everything works fine.
But for the stored access token, it shows one more comma which is not correct. It leads to misconfiguration if I just copy it and set up for another instance.
For example, my defined access token is "pRsavHKTaIphbt"
after configuration, the token shown in the extension configuration will be "pRsavHKTaIphbt,"
The above code is randomly generated.
