I dont have a specific example, but I do not understand this topic in general
On the June 2016 ACT, there were two questions on English section where they introduced someones position on a team/group and there were different answers with different comma placement
Like:
“Leader of his team, Riley, helped his team…”
are there commas for this?

is this the answer to my question
That is a very awkward sentence. If you remove the commas and Riley, you’ll find that the sentence reads “Leader of his team helped his team.” I know it’s an example, but you remove what is between the commas to see if the sentence reads correctly.
For example,
“Riley, leader of team Bravo, helped set the table.”
The sentence reads correctly when the appositive is removed: “Riley helped set the table”
No comma after Riley because you don’t put a comma directly between a subject and its verb, and Riley is the subject of the sentence. If the appositive (“Leader of his team”) comes after Riley, then it should be between two commas as it is grammatically unimportant information.
