I have a Slack app that opens a modal when someone from my team “rejects” a colleagues access request. The modal prompts the person rejecting the request to give a reason, and then the original Slack message in our channel is updated; the person who submitted the request is sent a Slack with the reasoning; the Zendesk ticket is updated with the person who rejected the request and their reasoning; and all of the events are logged in my SQL database.

slack block text_input not work in mobile app(only android).
// IOS is work!
