I am trying to work out how to turn on data labels that pop-up to tell you what arguments a function takes as you type an expression. So say if I type the following in the editor:
Table.SelectColumns(
I would see a popup that would look something like:
Table.SelectColumns(table as table, columns as any, optional missingField as nullable number) as table
Note, this is different from the info that shows the syntax for the function (before the brackets). So just to clarify I am not talking about the below label that pops up, but rather a popup for when you are trying to workout what the funciton takes INSIDE the brackets.
