I stream a PDF file from the ERP backend and display it in the sap.m.PDFViewer control. I have set showDownloadButton property value to "false". The download button has disappeared in the popup footer.

Unfortunately there is another download button in the integrated toolbar.

Can someone give me a hint on how to remove this button?

In fact, all I need is the rotate button.
