UFT One Digital Lab Lite - Firefox mobile Browser

We are using UFT One version: 23.4, Digital lab lite: 2021,. We are able to do mobile chrome browser automation using 

WebUtil.LaunchBrowser "MOBILE_CHROME", "lT-1", "cube", "ANDROID", "5.1"

But we are could do not find the parameter for Firefox E.g. Mobile_Firefox. Is there any string that we can use to automate mobile firefox browser.

Note: We used the following parameters, but it opens the desktop firefox browser
  • FIREFOX
  • FIREFOX64

Appreciate if there are any answers for this
