It really does involve connecting. There may be an interference operation that relies on creating content out of whole cloth, but if the content doesn't circulate, there will be no effect. People, the public, really have to be reached, whether by polarizing content or, on the other hand, by content that will confirm their opinion and incentivize them to share the content.
It can also be misleading content, whether using clickbait or by decontextualizing a situation in a way that does not correspond to the publication as such.
So there are several strategies for getting content to circulate. The people engaging in foreign interference still have to have a better understanding than we do of how the sociodigital media they are going to use, and those media's codes, work.
