Calling "fix geometries" in the QGIS python console?

I want to use the "fix geometries" tool in the Python console in QGIS.
However, I can’t find anywhere, how to function is called and how to use it as code.
I tried

QgsProcessingOutputVectorLayer(input_path, output_path)

But I guess this is wrong, since it does not work. Any hints?

import processing
layer = iface.activeLayer()
fix_layer = processing.run("native:fixgeometries", {'INPUT':layer,'OUTPUT':'memory:'})['OUTPUT']
