PyFluent APIs for iteration and exit doesn't work when Fluent server is launched from WB using PyWorkbench #2123

🐞 Description of the bug
PyWorkbench development recently added support for PyFluent. Through this, we can connect to Fluent server (on WB platform).
I was able to connect to Fluent server using this method and setup Fluent case using PyFluent APIs. However, when I try to start iterations or exit, it doesn't work. It seems that Fluent under WB platform performs additional operations before iterating or exiting (save case/date). That is why the PyFluent APIs are not working.
📝 Steps to reproduce
You may have to first install PyWB:
https://workbench.docs.pyansys.com/version/stable/installation.html
Following is the test code for PyFluent. Please execute. It doesn't work for iterations (line 34) and exit (line 37)
