Google Drive applications usually disable the browser right-click context menu in favour of the application specific context menu. However, it is still possible to access the extension actions by right-clicking in the right spot. We might revisit the way we provide access to these in a later update, but for now, this will have to do.
In Google Drive, right-click on the search field.
In Google Docs, right-click on the white space next to the document title.
In Google Sheets, right-click in the formula bar (or in a cell when editing).
In Google Slides, right-click in the formula bar (or in a cell when editing).
