how to remove a separator block

Using Gutenberg editor, I could not initially find how to remove a separator block. As I wrote this I found the answer.

In the editor, hover over the separator block. This shows, on the left of the block, the “move up icon”, the “6 dot drag icon” and the “move down icon”. Click on the “6 dot drag icon”. This selects the separator block. Then you see the “3 dots icon” above the block. Click on the “3 dots icon” to find the remove instruction.
