How to track the value of target function during ortools mixed-integer-programming solving process?

I'm using ortools SCIP to solve a really large mixed-integer-programming problem.

That problem costs more than 30 minutes.

The SCIP uses branch-cut-and-price to solve the mixed-integer-programming problem.

Each time, the SCIP would cut some branches.

So, my question is, how to print the value of the target function, after each cut(after each iteration)?
