[kostyanius]

Describe the bug
Hello. Sending from slack to discord channel messages with images and url, interactive buttons corrupts message content. see on the screens.

To Reproduce

1. add slack bot
2. add discord bot
3. add slack-discord default config (matterbridge.toml)
4. run matterbridge relay
   (docker, or installed via go it does not matter. i have tried both. the final result it the same - discord message is corrupted)

Expected behavior
