🔖 Feature description

I had someone ask me for this, and I am not sure if it is possible. But the slack integration adds a preview with what looks like very similar information from the message. This appears a bit superfluous and it would be nice to be able to disable this.

✔️ Solution

Add an option to the web gui to disable link and media unfurling.
https://api.slack.com/reference/messaging/link-unfurling#no_unfurling_please

Not really sure where the preview is coming from, it's not really media and not really a link. But this should prevent this from happening in the slack API/Webhook call:

{
    "text": "Check out the <https://api.slack.com|Slack API>",
    "unfurl_links": false,
    "unfurl_media": false
}

So a simple slider for "Disable Preview", "Disable Link Unfurling" in the slack integration edit menu with the other sliders should be functional and still look aesthetically pleasing. You could also do a single slider "No previews" or something instead.

❓ Alternatives

Not sure of any.

Looking at the code:
https://raw.githubusercontent.com/louislam/uptime-kuma/68f389868ca1f16893454ba16763498544aa8ace/server/notification-providers/slack.js

It appears this is from the attachment array in the data object:
"attachments": [...]

https://api.slack.com/reference/messaging/attachments#example

So a simple toggle to "Include Preview" or something similar, when disabled, removes:
data.attachments from the payload.

I would be willing to fix this issue with a pull request, once my pull request for #3351 gets merged :)

I would also love to hide these redundant previews!
@DaanMeijer Are you still up for a pull request? 🙂
