OptionalautoOptionalclassClass(es) for the panel root.
The function whose arguments are being filled. ONE function — this panel never searches (in the script editor there is nothing to search: the function is the one being written).
OptionalhomeThe anchor a bare reference (A1) resolves against and serializes bare for — normally the cell
the call is being inserted into. Without one the fields fall back to the workbook's selected
sheet, and the result evaluates against its own default cell.
OptionalonThe assembled call, on every change — =SUM(A1:A5,B1). The host is what inserts it; this panel
owns no action row (see the class doc).
OptionalworkbookResolution/evaluation context. Defaults to the enclosing WorkbookContext.
Take focus (the first argument field) on mount.
