Which coreference chains does each sentence relate to in NeuralCoref?

Hi, I am using neuralcoref for the task of coreference resolution in a text.

I want to know each sentence has mentions from which coreference clusters. For example, sentence1 has mentions from coreference clusters 1, and 4; sentence 2 has mentions from coreference clusters 10 , 14.

How can I do this?

Thanks in advance.
