How to create an ESDT token

Question

I try to create a fungible ESDT token. I am very new in MultiversX, so my understanding on creating token is: we will have to use TokenOperationsFactory class from this script.

First we have to use the IConfigure interface to instantiate the TokenOperationsFactory. Then we have to call the issueFungible(). Am I right?

If I right, then I am having these issues:

1. I don't know what will be values of parameters of IConfigure.

2. Is it necessary to provide values for all parameters? Because in docs I saw a instantiation is not using all required parameters value.

3. What is the value of esdtContractAddress from from this line?
