Android - Garmin Heart Rate Monitor

Hi All,

Apologies if this question has been already been answered before.

My computer is not working so I am setting up Zwift via my android phone. (Huawei P30 lite)
The one issue I have is pairing my Garmin Heart Rate Monitor (bit old - came with a Forerunner 410 watch) with Zwift. Everything else is paired via bluetooth.

If my computer was working I would plug in my USB stick & pair it that way.
Unfortunately, with the android the HRM & Zwift app aren’t pairing.
I installed the ANT+ app on my phone but still not pairing. (I have no way to insert the USB stick into my phone)
What am I missing?

Thanks in advance
