Hi @plshapkin, thanks for writing in!

Unfortunately, the lack of markdown format support is a known issue and we don't have any updates since the issue was initially reported. We cannot tell when and whether this can be improved in the future. See the similar ones:

• files_upload_v2 initial_comment doesn't accept markdown python-slack-sdk#1289
• Markdown doesn't work well with links on files.uploadV2 method node-slack-sdk#1561

The only workaround that I can suggest is to use chat.postMessage with files' permalink URLs: slackapi/python-slack-sdk#1194 (comment)

I know this is not a great answer but I hope this was helpful to you.

Hi! Thank you very much for your patience regarding this issue. The server-side has recently been enhanced, so now the API accepts mrkdwn format for the initial_comment parameter! Let me close this issue now 🙇
