 ### Fixes
 
 - Docs/Slack manifest scopes: add missing DM/group-DM bot scopes (`im:read`, `im:write`, `mpim:read`, `mpim:write`) to the Slack app manifest example so DM setup guidance is complete. (#29999) Thanks @JcMinarro.
+- Slack/Onboarding token help: update setup text to include the “From manifest” app-creation path and current install wording for obtaining the `xoxb-` bot token. (#30846) Thanks @yzhong52.
 - Slack/Bot attachment-only messages: when `allowBots: true`, bot messages with empty `text` now include non-forwarded attachment `text`/`fallback` content so webhook alerts are not silently dropped. (#27616)
 - Slack/Inbound media auth + HTML guard: keep Slack auth headers on forwarded shared attachment image downloads, and reject login/error HTML payloads (while allowing expected `.html` uploads) when resolving Slack media so auth failures do not silently pass as files. (#18642)
 - Slack/Security ingress mismatch guard: drop slash-command and interaction payloads when app/team identifiers do not match the active Slack account context (including nested `team.id` interaction payloads), preventing cross-app or cross-workspace payload injection into system-event handling. (#29091) Thanks @Solvely-Colin.
