How can I save the best model during the rtmo model training?

[nepulepu]

The default config is using CocoMetric as the evaluator, but during the on the checkpoint hook what is the "save best" metric that can I use to choose the best weight of the model as it stated

key_score = metrics[key_indicator]
KeyError: 'CocoMetric

if savebest='CocoMetric'

I am using config from this file:
RTMO-m
