Punctuation In Two Prepositional Phrases Using the Same Object

I'm trying to phrase a sentence with two prepositional phrases that use that same object. Specifically:

"This is due, in part, to my training of and good rapport with the team."

How should I punctuate this? Possibilities I've tried so far:

"This is due, in part, to my training of – and good rapport with – the team."

"This is due, in part, to my training of, and good rapport with, the team."

"This is due, in part, to my training of – and good rapport with –, the team." (This looks particularly wrong).

What is the grammatical rule to apply here?

I've seen the first way in academic writing. By the first way, I mean: "This is due, in part, to my training of and good rapport with the team."
