Looking to integrate button with block in Json [slack] - json

Question

I'm looking to integrate the button with block id using modal in slack, not able to successfully integrate so far now, not sure what I'm missing here also I'm a newbie in JSON so definitely might be missing something minor here. So basically when someone clicks the review button it should pop up with another form. I would really appreciate it if someone can provide some inputs here. Thanks in advance
Testing can be pretty much done here - https://app.slack.com/block-kit-builder
