 - `-m`: Matching ID, activation code. optional.
 - `-c`: Confirmation Code, optional.
 - `-i`: The IMEI of the device to which Profile is to be downloaded, optional.
+- `-a`: LPA qrcode activation code string, e.g: `LPA:1$<sm-dp+ domain>$<matching id>`, if provided this option takes precedence over the `-s` and `-m` options, optional.
