How can I forward k6 cloud metrics to Grafana prometheus

We use K6 github action to run browser tests in cloud. K6 cloud, collects metrics automatically and is visible for the dashboard but it’s not available for alerting. k6 run offers -o experimental-prometheus-rw option to forward metrics to prometheus when run locally but k6 cloud does not have -o option. Is there a way we can forward the metrics collected in k6 cloud to hosted Mimir instance, so we can create alert against it ?
