How can I get the maturity of a Neuron?

I used the commands described here: Neuron/ICP Instructions for Seed Participants :: Internet Computer
To find out more about individual neurons. But I can only get:

  • dissolve_delay_seconds
  • recent_ballots
  • created_timestamp_seconds
  • state
  • retrieved_at_timestamp_seconds
  • voting_power
  • age_seconds

But how can I get the maturity?


Couldn’t find anything either

would also like to know, has anyone figured this out?
