Canon – Small spots on the EOS m50 sensor

I had opened my Canon EOS m50 lens while on a ferry to a nearby local island. Once I got home I saw few points on the sensor that don't look like dust. I used swabs and cleaned the sensor to make it clean, but even if I took photos with a high separation value like f20 and higher, I can see that there are still points of light and that I can't eliminate with wet cleaning. Any idea what should I do now?

So here I have 2 images. The first one I took in the f30 of the white wall of my kitchen and the same image made a dazzle in the light room. After fading the points are visible.
