Generating UUID(unique ID) at joining points

I have road network (lines) and points (Address) . With the help of closestSegmentWithContext function, I join points to nearest lines in QGIS. Is there a way to to generate a unique ID at every joining point as the joining points are drawn manually in below image.

What I have researched so far:

• Found a possible solution here, but it didnt worked for joining points.
• I come accross a useful plugin "AUTOFIELD" in anwer here, but this plugin is no more avaible in QGIS 3.XX

The code for joining line segements to nearest points is given below and shape files are available here:

roadlyr = QgsProject.instance().mapLayersByName('TR_ROAD')[0]
addrlyr = QgsProject.instance().mapLayersByName('ADDRESS')[0]

#List all features
adresses = [f for f in addrlyr.getFeatures()]
roads = [f for f in roadlyr.getFeatures()] 

#Create empty vector layer
vl = QgsVectorLayer("LineString?crs={}&index=yes".format(roadlyr.crs().authid()), "myLayer", "memory")
provider = vl.dataProvider()

for adress in adresses:
    a = min([road.geometry().closestSegmentWithContext(adress.geometry().asPoint()) for road in roads], key=lambda x: x[0]) #For each road find closest address
    gLine = QgsGeometry.fromPolyline([QgsPoint(adress.geometry().asPoint()), QgsPoint(a[1])])
    f = QgsFeature()
    f.setGeometry(gLine)
    provider.addFeature(f)

QgsProject.instance().addMapLayer(vl)
