Replace dot with comma

Question

I have next code in Google App Script, adding values with comma works fine, but when i want replace dot with comma this code doesent work. Tried many variants of replace none of it helped.

let enter, stop, pose, enterD, stopD, poseD;
if (regexpLongDec.test(text)) {       [_,enter, stop, pose] = text.match(/L\s+(\d+(?:[\,]\d+)?)\s+(\d+(?:[\,]\d+)?)\s+(\d+(?:[\,]\d+)?)$/); }
if (regexpLongDecLong.test(text)) {       [_,enterD, stopD, poseD] = text.match(/L\s+(\d+(?:[\.]\d+)?)\s+(\d+(?:[\.]\d+)?)\s+(\d+(?:[\.]\d+)?)$/); 
                                         enter = enterD.toString().replace(".", ",");
                                         stop = stopD.toString().replace(".", ",");
                                         pose = poseD.toString().replace(".", ",");
                                        }
        
      expenseSheetLong.getRange('B2').setValue(pose);
      expenseSheetLong.getRange('C2').setValue(enter);
      expenseSheetLong.getRange('D2').setValue(stop);
