How to use ccsh sonarimport with ssl certificate?

[ngerbode]

Hi, I am new to ccsh and wanted to test the sonarimport. Our company's sonarqube is internal and uses a self signed certificate. How can I tell ccsh to use that certificate?
Me first try without certificate ends in following exception:

ccsh sonarimport "https://sonar.xyz" "XYZ" "--user-token=sqa_XYZ" "--output-file=test" "--not-compressed" "--merge-modules=false"
