Very tricky in the middle part, but once broken it was lovely and smooth. Very pretty puzzle too

This puzzle has many solutions. The mod 3 constraint is just not strong enough to lead to a single solution here.

I checked with a solving tool and there seems to be a unique solution. What would be another solution?
