Using shinytest with another headless brower


I want to use shinytest to test the UI of my shinydashboard. However, I need to install PhantomJS as dependency. PhantomJS development is suspended for a few years already. Therefore, we rather do not use this headless browser. Is there a way to use another headless browser (Chrome for example) as the dependency in shinytest? If so, how can I tell shinytest that it should find and use this other headless browser?

Thanks in advance!
