How to configure 32kHz LSE oscillator via HAL?

I think I've set up everything sensibly via STM32CubeMX to get HAL control of the LSE, but the external oscillator appears to be not operable. In particular, there is essentially no voltage on the 32kHz crystal pins, so of course it will not oscillat...
