python - Programmatically styling layer after output is returned from QGIS 3 processing script?

Hi this may be more of a python question rather than qgis processing script question. I've managed to successfully get the output that I want from my processing script, but I wish to take one step further and style it automatically with a saved qml file.

The code below doesn't work because the return ends my script. How should I go about doing this?

return {self.OUTPUT: dest_id}
iface.activeLayer().loadNamedStyle('Buffer.qml')
iface.activeLayer().triggerRepaint()
