Is there are way to retrieve heart rate bpm and confidence by calling a function rather than using a listenner ?

I am wondering if there is a way to retrieve the heart bpm and confidence values by polling rather than using a listenner. In a multiclock format - the problem for me is variables being out of scope when the listenner gets called. I can do it with a listenner (as I have done with GPS fixes that I wanted to share between two multiclock watch faces) but it would be much simpler if I could just do

` let bpm = HRM.getBpm(); let confidence = HRM.getConfidence();
