Activates the remote action.
This is the same as activate_action except that it allows for provision of "platform data" to be sent along with the activation request. This typically contains details such as the user interaction timestamp or startup notification information.
platform_data must be non-null and must have the type
g_variant_type_vardict. If it is floating, it will be consumed.
