Showing a local variable in the wave window?

For others coming after, here is the solution:

• Update: in Questa Intel FPGA Edition, you go to Compile/Compile Options, then select the Coverage Tab under "Other Coverage" (the 4th box in 21.1), is an option "Enable Finish State Machine Coverage (+cover f)". If you select that, then hop out of questa and back to quartus and restart questa - yes I'm sure there is a quicker way to do that - then the process in https://nandland.com/view-variables-in-modelsim-waveform/ works - the state, which is a variable, shows up.
