Have there been any legally held demonstrations against the war (or against the “specially military operation”) in Russia?

I'm well aware that Russian authorities have cracked down on spontaneous/illegal anti war demonstrations. Whereas for the pro-military-intervention ones, e.g. using the "Z" sign...

Have any Russian authorities granted any permits such anti-war/anti-military-intervention demonstrations to be held legally? If, so what kind of banners were allowed at such legally held anti-war demonstrations? I'm talking about the war in Ukraine, so was e.g. "stop the special military operation" a banner that was seen at a legally held protest in Russia, for instance?
