Katalon & Appium

I want to run a mobile test case in firefox Focus but I don’t know how I can configure, I made one custom execution but when katalon starts the connexion with appium, appium use their configuration and use chrome browser by default. Do you know how I can change this configuration?

You can’t run your test scripts on Firefox browser under your device using Appium. Appium does not support this: https://github.com/appium/appium/issues/8651. Only Chrome can be used in this case
