[macOS][Agent&Skills] MS Teams bot @mention renders raw AAD object ID instead of a display-name mention #5852

Mirrored from NVBug #6381274 — filed by the NVIDIA QA team.

Description

When the MS Teams bot tries to @-mention a user, the reply shows the raw Entra/AAD object ID as text instead of rendering a proper Teams @mention chip with the person's display name. The mention also does not render as a real (highlighted) Teams mention.

Environment

Device:        MacBook (Apple Silicon)
OS:            macOS 26.5.1 (Build 25F80, Darwin 25.5.0)
Architecture:  arm64
Node.js:       v23.10.0
npm:           11.3.0
Docker:        27.4.0 (build bde2b89)
OpenShell CLI: 0.0.44
NemoClaw:      v0.0.68
OpenClaw:      2026.5.27 (27ae826)   [sandbox 'lynnteams', model nvidia/nemotron-3-super-120b-a12b, CPU sandbox]

Steps to Reproduce

1. Onboard a sandbox with the Teams channel; set TEAMS_ALLOWED_USERS to AAD object IDs.
2. In a group chat, ask the bot "can you tag me?".
3. Observe the rendered reply.

Expected Result

Reply contains a proper highlighted Teams @mention showing only the display name (e.g. "@san Dang"), no raw ID visible, and it pings the user.

Actual Result

Reply shows the raw AAD object ID as literal text, e.g.:

@
San Dang (205f29da-231e-4a0e-a0b2-b398e6302087) I've tagged you!

The "@" is not a real mention chip and the raw UUID is exposed to the user.
