To add each parameter to the queryString concatenate an "&" symbol, the name of the parameter, the "=" symbol and the value for the parameter, following this format:
...&password=myPassword&clipboard=false...
These parameters will be considered only if you are not using a profile as a template or if you configure the overrideDefaults setting to true (see the "Mode 2" on the Configuring the connection section, for more details)
