Publish to SAP Lumira Server - Missing button

Hello,

I'm using Lumira Desktop 1.29.3 and I can't publish any document to our BI platform (4.1 SP6 patch5)

I followed the explanation here: https://youtu.be/skP2u_yGnl4

The connection to our Lumira Server works fine

But I simply just don't have the "Publish to SAP Lumira Server" button on the "Share" tab

The only options are "Export as File", "Publish to SAP HANA" and "Publish to Explorer"

What did I miss?

Thanks,

Guillaume
