[BUG] Discord plugin: "See more" on permission prompts immediately shows "Details no longer available"

Bug Description

When a permission prompt (e.g. "Permission: Bash") appears in Discord DMs via the channels plugin, clicking the "See more" button immediately responds with "Details no longer available" — even when clicked within seconds of the prompt appearing.

This makes it impossible to view command details before approving or denying. Users are forced to blindly approve commands they cannot inspect.

Steps to Reproduce

1. Run Claude Code with --channels plugin:discord@claude-plugins-official
2. Trigger a bash command that requires permission approval
3. Permission prompt appears in Discord DMs: "🔓 Permission: Bash" with "See more", "Allow", and "Deny" buttons
4. Immediately click "See more"
5. Discord shows: "Details no longer available"

Expected Behavior

Clicking "See more" should display the full command text (e.g. the bash command being requested) so the user can make an informed approve/deny decision.

Actual Behavior

"Details no longer available" appears instantly, regardless of how quickly the button is clicked after the prompt appears. The interaction response appears to fail immediately — this is not a Discord interaction timeout issue (those expire after ~15 minutes).

Environment

• Claude Code v2.1.111
• Discord plugin: discord@claude-plugins-official
• Running on Linux (Debian) as a systemd service with --channels
• Tested from both desktop Discord and mobile Discord

Screenshots

!Permission prompt with See more button
The prompt shows "Permission: Bash" with See more / Allow / Deny buttons.

!Details no longer available
Clicking "See more" immediately shows "Details no longer available."

Note: Screenshots available — the "Details no longer available" message appears even when "See more" is clicked within 1-2 seconds of the prompt appearing.

Impact

This effectively removes the user's ability to review commands before approving. Combined with the lack of inline command display (see #50034), there is currently no way to see what command is being requested before approving via Discord. Users must either:

• Blindly approve everything (security risk)
• Deny everything and check the terminal manually (defeats the purpose of remote management)
