iain_constrained_sharpen command not found by gmic CLI (2.9.4)

Even though ~/.config/gmic/update292.gmic defines it:

repeat $! l[$>]
nm=${-gui_layer_name}
sharp_radius=$1
amount=$2
threshold=$3
constrant_radius=$4
overshoot=$5
channels=$6
value_action=$7
apply_channels "
sharp_radius=$1
amount=$2
threshold=$3
constrant_radius=$4
overshoot=$5
+dilate_oct[0] $constrant_radius
+erode_oct[0] $constrant_radius
unsharp[0] $sharp_radius,$amount,$threshold
add[1] $overshoot
sub[2] $overshoot
blend[0,1] darken,1,0
blend[0,1] lighten,1,0
blend alpha,1,0",$channels,$value_action
nm name($nm)
endl done

The gmic file defines the GUI.

• So...If not using gmic gui, does this script have to be processed manually?
