Is there a way to accept either of two flags. only one valid at a time

What's wrong

Is there a way for app to accept either of two flags. If one is given app shouldn't accept second, vice versa.
ex

App::new("tool")
    .arg(Arg::with_name("primary"))
    .arg(Arg::with_name("secondary"))

Here imagine tool can either act as primary node or secondary node. If it's started with

$ tool primary

it shouldn't accept secondary flag. to solve this normally we would write manual logic in code but I was thinking is there a way to do this in clap? I read something about conflict not sure if it's the same thing, as I couldn't find much information on it (both docs and examples don't elaborate anything on it if I am right)

You can use either conflicts_with or ArgGroup:

Perhaps the most common use of ArgGroups is to require one and only one argument to be present out of a given set.
