Katalon Recorder global variables

I create a js file that contains the variables, then I just send the varible

a file user-extensions.js is recreated and it is only uploaded in the interface of katalon ide
the file contains the following code for example:

storedVars [“varName”] = “”;
storedVars [“varPass”] = “”;
storedVars [“varBanOw”] = “”;
storedVars [“varPassOw”] = 123 + 5;

Then you get the value of the varible as follows:
Command: click
Target: css = input [type = text] #MyTextBoxID
Value: $ {varName}
