A sidebar only extension for the Opera browser

The developers of the Opera browser have made a change in how it handles extensions. Previously, it was possible to write an extension that would put icons on both the Menu bar and the Sidebar. The change to opera defines two different types of extension, one for the Menu bar, and one for the Sidebar. The Bitwarden extension that Opera is currently using only shows icons on the Menu bar. There is no extension for the sidebar. Please develop a sidebar extension for Opera
