Context menu commands can't be used without Send Messages permission

[Luc1412]

Description

It seems like since the backend support for user commands had been added, context menus doesn't work if the user got no send messages permission.

I think these commands should at least work, when the response is ephemeral.

In our case we got a feedback system, where users fill modals with there feedback and webhooks post it, so the users itself got no write perms. However they should be able to report feedback trough context menus, which doesn't work now.

Steps to Reproduce

1. Setup a Context menu command
2. Setup a channel where a user can't send messages, but can use app commands
3. Execute the command as the user with no write permission

Expected Behavior

The command will be normally (ephemerally) executed

Current Behavior

The command can be used, however an "Missing Permission" error appears:

Also after switching the channel and going bac, the messages changes from "Missing Permissions" to "The application did not respond":

No response

Hey! Just a few questions to better understand this:

• Is the application you're using installed to the server or to your users? (docs)
• Was this working in your server before and broke, or is this more of a feature request?

I see the frontend has a couple bugs reported here where it's letting you try to run commands that will fail due to permission checks, and changing channels is losing the reason for it failing, but I want to double check if there was a recent backend breakage in here too.

context menu commands are supposed to not work without Send Messages, except user-installed commands, which are forced ephemeral. They worked for guild-installed commands for a short while (few weeks?) but this was considered a security issue, as it could create public messages in read-only channels, and was blocked in the backend last week as a bug fix.

This is a good old classic server app.

I think I never tested it myself, however another dev that contributed to the bot told me it was working fine.

as it could create public messages in read-only channels

As long the context menu is ephemeral only, it should be fine too. This could also be forced, instead of letting it fail with an error message,

[sklein12]

As many of you have mentioned this is is a feature request to force guild apps responses to be ephemeral. I've updated the issue to reflect that. This is something we've actually decided against doing because it would be considered a breaking change.

We could potentially look at other ways of doing this in the future so I'm going to leave this open as a feature request.

My server has a custom context menu command to report messages to staff members of the server, just today members were confused why they couldn't report messages in our #welcome channel.

I would appreciate some sort of change that would allow ephemeral responses to be possible, as it's confusing that the app command is available to be used there, but doesn't work and just errors out.
