If Slack integration is enabled for your organisation, you can check-in to the OKRs for any time period from within Slack by following the below steps:
Type “/ally list <time period name> OKRs” in Slack window. This will display all OKRs in the given time period.
Now, enter “/ally checkin” in the Slack window and you will be able to see the OKRs for that time period to be checked in.
You can list OKRs from any time period(and switch back to the current time period) in a similar way and make check-ins as required.
