Display Temperature Chart for Multiple Sensors on one Chart / Screen

How can I see the temperature for multiple sensors on the same screen / chart?

I want to be able to see the temperature for at least 2 of my sensors on my IBS-M2 at the same time.

I expected to be able to do this with the Inkbird app, based on the screenshots that show multiple temperatures on the one screen - but now I realise that’s not how it works with my sensors connected to the IBS-M2 as sub-devices.

I hope you can tell me how to do this now.
