Workflow does not have 'workflow_dispatch' trigger.

[rolfTurner]

I keep trying to run rhub::rhub_check(platforms="windows") and it keeps finding new ways to frustrate me. The output I get is as follows.

 library(rhub)
 rhub_check(platforms="windows")
✔ Found git repository at /home/rolf/Rpackages/Kanova/kanova.
✔ Found GitHub PAT.
Error in `rhub_check(platforms = "windows")`:
! :( Failed to start check: Workflow does not have 'workflow_dispatch' trigger.

How can I arrange for my "workflow" to have "workflow_dispatch trigger"???
(I must confess that I have no idea what a "workflow" actually is.)

This problem seemed to come out of the blue. In all my previous attempts at using rhub_check() no such error was thrown. Then suddenly ....

You deleted the rhub.yaml workflow file: rolfTurner/kanova@0831a8f#diff-66448eff86c4360e3d463a58ea3f83d0902a32e4f61a0007e212f91e5fffdd32
rhub_check() does not work without this.
You can run rhub_setup() to crete it again.
