+## MM-T5526: Non-channel-admin users can use message links in private channels
+
+---
+
+**Step 1**
+
+Preconditions:
+
+1. Ensure that the Mattermost instance is accessible.
+2. Make sure normal users do not have permissions to manage private channel members.
+3. Have at least two users available: one as the channel admin and another as a member without admin privileges.
+
+Test Steps:
+
+1. Create a private channel with the channel admin user.
+2. Type a message in the private channel using the channel admin user.
+3. Select the message posted by the channel admin user and use the "Copy Link" option.
+4. Paste the copied link in the same private channel.
+5. Add another user (non-admin) to the private channel with member permissions.
+6. Log into Mattermost with newly added user's account.
+7. Navigate to the channel and click on the message link.
+8. Verify that the non-admin user can access the message by clicking on the link without encountering any errors.
