Discord: a slash-command-only bot needs no privileged intents at all, and often only Send Messages, Embed Links and Use Application Commands.
Telegram: bots in groups see only commands and replies by default (privacy mode). Admin rights are only needed for moderation features.
Slack: every scope is shown to the installing admin. Fewer scopes mean faster approval.
