When I run pulumi up against our azure webapp I see this:

~ siteConfig: {
    ~ appSettings: [
        ~ [18]: {
            ~ value: [secret] => [secret]
            }
        ~ [21]: {
            ~ value: [secret] => [secret]
            }
    ]
}

How can I find out what values are going to be changed? It would be good to at least know the appSettings keys, but there doesn't seem to be a way to get any more info than this.
