to become the/- President

Hey, I’ve been wondering what to do with these sentences that contain a reference to a title held by one person at a time, such as the Pope, President, Prime Minister etc. What do you say I do?

He became the Pope/President/Prime Minsiter.

or

He became Pope/President/Prime Minister.

Personally, I’d opt for the latter because I know that in phrases like “He was elevated/promoted to…” we wouldn’t put an article before the name of the title.

I would also opt for the latter, especially when there is no “of…” after President, Prime Minister, etc.
