need help laying out dynamic paint setting in toolbar.

For Dynamic Paint, I can’t seem to figure out how to layout paint distance for the brush settings in the toolbar as its own panel.

Any python wizards that can do this? Thanks.

 
        ob = context.object
        if ob is not None:
            for mod in ob.modifiers:
                
                if mod.type == 'DYNAMIC_PAINT' and mod.ui_type == 'BRUSH':
                    

                    brush = mod.brush_settings
                    
                    split = layout.split()

                    col = split.column()
                    col.prop(brush, "paint_distance")
