SRAM components question

Following an unfortunate interface probem between my handlebar, my ribcage and a badly subsided country road, I find myself in need of a new SRAM Rival 22 brake lever.  Right side (front), rear mech.

Interestingly, the brake works fine.  The shifter, well, that’s another story…

I’ve been looking around the internet and can find only lever + caliper combos (it’s rim hydraulic).  I’ve emailed Zyro Fisher and will also contact Raleigh, but has anyone else had this problem?  It would be a bit unfair if I couldn’t just buy a lever on its own.
