Wyze scale missed syncing some data to Apple health

I have a Wyze scale that in general has synced its data to the Apple health app. At some point, it stopped syncing without me realizing it. I can manually export out the 8 months of missing data from the Wyze app. I’m not seeing a way to import in that exported data into Apple health. I only see a way of adding one data point at a time.

does anyone know how to import the exported file?

I have turned syncing back on so that it will sync from this point forward, but I don’t think it syncs backward for the eight missing months.
