Allow to mention Attachment in Rich text (uploaded files)

[Beeditor04]

Scope & Context

Example:

1. Able to mention Attachment like how you mention Opportunity / Task / People / ...

2. Able to get the link of Attachment to share, and paste the link in Rich text automatically change to mention again.

Current behavior

1. Cannot enable to "Global search" in setting (which I'm able to mention with @)

2. If user upload at Files, there is no way to mention this file in Rich text (for report, changelog, description,...)

3. Workaround I can think about is visible the Attachment object, then get the url link of the record, which is still very annoyed.

Expected behavior

• @ will able to mention the Attachment
• Able to get the link of the Attachment

Kind: Probably a feature request. Attachments are not currently available as @ mentions, do not expose a convenient shareable record link, and pasted attachment links are not converted into mentions.
Severity: UNDEFINED because this requests new mention and link-conversion capabilities rather than reporting a regression or broken existing feature.
Implementation hypothesis (medium confidence): packages/twenty-front/src/modules/mention/hooks/useMentionSearch.ts only searches active, non-system, searchable objects; Attachment is therefore excluded. Supporting it would also require attachment-aware rendering/link parsing around packages/twenty-front/src/modules/mention/extensions/MentionTag.ts.
The desired behavior is clear; acceptance details are still needed for attachment permissions, link visibility, and behavior when a recipient cannot access the file.
