How to identify the calling feature file for step definition?

[sachingainewar]

To make reuse of step in a new feature.

A1.feature
Then I click on "Save" button

B2.feature
Then I click on "Save" button

Common step definition

const A1= require('../../../support/locators/A1-loc.cy')
const B2= require('../../../support/locators/B2-loc.cy')


Then ('I click on {string} button', (buttonName)=>{
    clickOnButton(getButtonLocator(fromButtonNameAndFeatureFileName)
})

I want to choose the different locators for save button base on different feature file. Means if A1.feature file calls then point to A1-loc.cy and if B2.feature file calls then points to B2-loc.cy

I have No idea , how to identify the calling file? And below functions works perfectly well for the same. But calling from feature file, No idea. Kindly help me..:

module.exports._getCallerFile=()=> {
   var filename;

   var _pst = Error.prepareStackTrace
   Error.prepareStackTrace = function (err, stack) { return stack; };
   try {
       var err = new Error();
       var callerfile;
       var currentfile;

       currentfile = err.stack.shift().getFileName();

       while (err.stack.length) {
           callerfile = err.stack.shift().getFileName();

           if(currentfile !== callerfile) {
               filename = callerfile;
               break;
           }
       }
   } catch (err) {}
   Error.prepareStackTrace = _pst;
     console.log(filename)
   return filename;
}
