How do I call a mailApp function within an onEdit function? - google-apps-script

Question

I have an onEdit function where if executed should send an email. However, some research has turned up that the mailApp functions don't work with onEdit. I'm currently toying around with workarounds but wondering if others have solutions they've come up with.
function onEdit(e) {
var sheet = e.source.getActiveSheet();
var sheetName = sheet.getName();
//if editing specific sheet
if (sheetName == "draft_test" ) {
//if editing 6th column
var r = e.source.getActiveRange();
if (r.getColumn() == 6 ) {
var player = sheet.getActiveCell().getValue();
// Display a dialog box with a message and "Yes" and "No" buttons.
var ui = SpreadsheetApp.getUi();
var response = ui.alert('Do you want to draft '+player+'?', ui.ButtonSet.YES_NO);
// Process the user's response.
if (response == ui.Button.YES) {
//***********FOR SOME REASON EXECUTING THIS FUNCTION ISNT WORKING******************
emailLeague();
//sortAutoRoster();
} else {
}
}
}
}
function emailLeague() {
var draftSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("draft_test");
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("test_email");
var emailSheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Manager Info");
//actual email address omitted
var recipient = 'emailaddress#gmail.com';
//get array of all picks on "draft test" tab, and find latest one
var picks = draftSheet.getRange(3,6,146,1).getValues();
for (var i=0; i<picks.length; i++){
if (picks[i] == ""){
var latestPick = i;
break;
}
}
var subject = sheet.getRange(i+1, 2).getValue();
var body = sheet.getRange(i+1, 1).getValue();
MailApp.sendEmail(recipient, subject, body);
}
