Not able to to usd bluepill fastlane

[avinashnarra]

Trying to use https://github.com/tbrand/fastlane-plugin-bluepill.But found out scheme option is no longer valid and only xctestrun would suffice.But it gives me an error stating "scheme is required",
but if use scheme it gives me below error

[!] Could not find option 'scheme' in the list of available options: xctestrun, output_dir, app, device, headless, number_of_simulators, reuse_simulator

So could you please help me with this issue, so that we can leverage this plugin.
