Link unfurling added by github bot despite settings to disable link preview

[ignaspa]

Describe the bug The github bot adds link unfurling despite me having my slack settings set to disable link previews. What does this mean? It means usually when I paste a link into a message, when I send the message no additional link preview is taking up space. However, when I send a message which includes say a github PR hyperlink, the github bot goes and adds a link preview which I then I have to wait for and remove manually. See screenshot:

See conversation with slack support

To Reproduce Steps to reproduce the behavior:

1. Go to slack Preferences > Messages & Media and disable Show text previews of linked websites
2. Ensure you have the github bot integration running in your slack workspace
3. Send a message with a github link, such as PR
4. After sending the message, the message will promptly be expanded by github bot with a link unfurl (in this case showing the PR title and description)
5. Press the little x in the top left of the preview to remove it

Expected behavior if I have the setting of link previews disabled I do not expect github bot to create previews (which I then manually have to remove) without my consent.

Screenshots See description above (screenshots inline)

Desktop (please complete the following information):

• OS: MacOS Version 14.1.1 (23B81)
• Browser: not relevant, but chrome
• Using the slack desktop app (up to date)

My shop has a culture of not wanting the GitHub links unfurled. We waste time EVERY SINGLE DAY following up every message of ours containing a GitHub link and quickly hitting the 'x' button to declutter a conversation, channel, or thread.

That the bot neither honors our personal setting, nor can be communicated with on a per-user basis to one-time opt-out of automatic unfurling is infuriating.
