Chai expect one out of two properties have a value

Is it possible doing in Chai something like?:

expect(message).to.have.property('key1', value).or.to.have.property('key2', value);

So I mean, property one OR property two have the value.

This could work as long as value !== undefined and message exists

expect([message.key1, message.key2]).to.include(value);

Alternatively you could use satisfy:

expect(message).to.satisfy(msg => {
    if (msg.key1 && msg.key1 === value) return true;
    if (msg.key2 && msg.key2 === value) return true;
    return false;
})

Satisfy
