Apparently my query is not a common one as I can't find an answer anywhere.
In order to have a particular widget on the team dashboard I need to have a filter which lists all issues where some time has been logged by a (developer) member of a specific tempo team.
Obviously to find the time logged by, I thought to use the worklogAuthor function
The problems is I can't find what to put next
I've tried IN() with both the tempo team name and the tempo team ID,
I've also tried the additional functionals of Membersof() and Team()
but none of them recognise the Tempo Team that we use for time logging!
