Load a list of synonyms in Bibliometrix: Can someone help me?

I was wondering if the community has an answer for the correct way to create a command to load a list of synonyms in Bibliometrix?

When uploading a TXT file to the synonym list, Bibliometrix only reads the first line.
In Bibliometrix there is information that a return separator must separate the lines.
I need help finding information on which return separator to use.
