Action doesn't send payload if deep link in url prop

Description

Hi, the button doc says If you're using url, you'll still receive an interaction payload it is actually the case except if the value of url is a Slack deep link, so :

{
	"type": "button",
	"text": {
		"type": "plain_text",
		text
	},
	action_id
	url:  `https://mysite.com`
}

sends a payload, but

{
	"type": "button",
	"text": {
		"type": "plain_text",
		text
	},
	action_id
	url:  `slack://app?team=${team_id}&id=${app_id}&tab=message`
}

does not. Is this a bug or a documented behavior or am I missing something to make it work? I am 99% sure it was actually sending a payload last week.

edit: Just upgraded to Bolt 2.0 (congrats for the release 🎉) but the result is the same. I guess it has to do with Slack API?

Thanks for your help.

@gterras Thanks for reporting this. I’ve confirmed a link button with a Slack deep link doesn’t send a block_actions event to Slack app’s request URL. I will share this feedback with the team concerned.

app.command("/show-buttons", async ({ ack, body }) => {
  const apiAppId = "A12345678";
  const text = {
    "type": "mrkdwn",
    "text": "click the button"
  };
  await ack({
    blocks: [
      {
        "type": "section",
        "text": text,
        "accessory": {
          "type": "button",
          "action_id": "deep-link-test",
          "text": {
            "type": "plain_text",
            "text": "deep link"
          },
          "url": `slack://app?team=${body.team_id}&id=${apiAppId}&tab=message`

FYI I got confirmation from Slack support that this issue was fixed for all OS.
