How to Replay a Activity after failure from externally

How can i replay the activity after failure. use-case is if some workflows get failed due to activity failure. how can i replay those failed activities externally. @tihomir @maxim

We don’t recommend failing workflows on activity failures. Activities can be retried as long as needed in Temporal.

If workflow already failed, then you can use the reset feature to restart it from a point before the activity invocation.
