Why is the Simulink Real-Time "Target Scope" block not available in R2020b or later?

There is no more "Target Scope" block shipped with Simulink Real-Time R2020b or later releases. It used to be available in 'Graphical' and 'Numerical' modes.
How can I visualize or display the signal data on a screen connected to my Speedgoat target computer in newer releases?

Simulink Real-Time went through a major product update for the R2020b release. Graphics support has been removed as part of this in favor of a more performant SSH shell-based QNX real-time operating system. This means that it will not be possible to visualize signals on the target screen anymore.
As a workaround, visualize the data and signals on the host computer using one of the methods below:
1) Use Simulink Data Inspector (SDI) to observe signals that you have marked for logging inside your model or using Simulink Real-Time Explorer: https://www.mathworks.com/help/slrealtime/ug/minimize-data-loss-with-simulation-data-inspector-buffered-mode.html
It is also possible to add and remove signals from SDI during runtime without requiring a rebuild, as explained in the MATLAB Answers post below: https://www.mathworks.com/matlabcentral/answers/1566953
2) Add a Simulink Scope block in your model and start the simulation using the "Run on Target" button: https://www.mathworks.com/help/simulink/slref/scope.html
3) Design an App Designer instrument panel app to stream data using instrument objects. Below is an example of such an app: https://www.mathworks.com/help/slrealtime/ug/add-app-des-app-to-inverted-pendulum-mdl.html
It will still be possible to connect a monitor to the target machine. A text-based status log will be visible on the target screen:
To replicate a Target Scope in 'Numerical' mode, printing to the target machine status monitor might be a feasible workaround. An example can be found in the following link:
