meaning

“We don’t have to look at the marshmallow. ”

There is a marshmallow in view (a type of soft confection).
We are not required to look at it.

Thank you for the quick reply.

Is this an idiomatic expression?

And the meaning is that we have to pay attention to more important things than those small tribal things like marshmallows?

emilkyIs this an idiomatic expression?

I have never heard anything resembling it as an idiom.
I have no idea if the writer has some allegory in mind, because there is no more context.

Don't pay attention to trivialities:
There is a book on the subject titled "Don't Sweat the Small Stuff"

I understand.

I've just found that the marshmallows are used in the first paragraph in the passage , and that those are used as a metaphor.

Thank you.
