Add-in does not appear in toolbar

Add-in does not appear in toolbar (Fusion 360 2605.1.52, Windows 11)

Hello,

I am trying to use your add-in with Fusion 360 version 2605.1.52 (Student) on a Windows 11 machine.
Unfortunately, the add-in does not appear in the toolbar after installation.

Expected behavior

The add-in should appear in the toolbar (as shown in various tutorial videos) and be accessible via the S shortcut search.

Actual behavior

• The add-in does not appear in the toolbar
• The add-in does not appear in the S shortcut search
• No error messages are shown

Screenshots

Toolbar – add-in missing

Add-In Manager – add-in enabled

Expected panel location (from tutorials)

What I have tried

• Restarted Fusion 360 multiple times
• Installed the add-in from GitHub
• Installed the add-in using the Fusion Add-In Installer

None of these steps resolved the issue.

Fusion log output

The Fusion logs do not show any errors, only that the add-in is being loaded:

Do you have some idea, why it not getting displayed?
Thank you!
