I want to plot a complex-valued function of two arguments in not Re/Im separete plots but a single plot where the absolute value and phase of the function are represented as lightness and color.
For this purpose, I found an ideal mathematica package by Dr. Bernd Thaller:
VQM packages: https://vqm.uni-graz.at/notebooks/index.html
Usage example: https://www.mathematica-journal.com/issue/v7i2/articles/contents/thaller/html/
I installed this package and tried to load it but it gave me the following error messages:
<< VQM`ComplexPlot`
Get::noopen: Cannot open Utilities`FilterOptions`.
Needs::nocont: Context Utilities`FilterOptions` was not created when Needs was evaluated.
To work around the errors, I tried a solution given for another solution but it didn’t work:

My question is how to modify the package to use on Mathematica11?
