The Inovelli Blue (and latest-gen Red) drivers are available from Inovelli in Hubitat Package Manager -- there is no native driver available for either.
This Mini-Dashboard app should still work for Blues AFAIK (I used to use it for mine, but have since moved to using Rule Machine instead), but the community developer of this app is no longer active with Hubitat, so this app has not been updated in a long time -- maybe it still works fine overall, but it's unsupported.
Here is Inovelli's support page for setting up Blue and Red led notifications in Hubitat:

ETA -- here is another very solid option for a community-developed Blue driver -- this one strips out the extraneous fan-related and other not-commonly-used parameters, so it's less intimidating to manage for most basic users (as compared to Inovelli's driver):
