Cannot set external pipeline job to allow_failure: true

Hi, I would like to allow the external job that is coming back from sonar with the results to have allow_failure: true (yellow exclamation mark in Gitlab)

I have tried the option `-Dsonar.gitlab.quality_gate_fail_mode=warn` and a combination of `-Dsonar.qualitygate.wait=true -Dsonar.gitlab.failure_notification_mode=exit-mode` but it still fails the pipeline.

Is this possible?
