How to remove values from a JSON Object

I have JSON object, i want to delete only value if exists.

My JSON Object

const users = {
  '115': [ 'HWac6RFhKhVWzByOAAAD', '0ETr8Jr0rpt64nqlAAAF' ],
  '116': [ 'RrkyrEIQl78X25XLAAAB' ],
  '117': [ 'rkyrEIQl78X25XRrkade', '78X258Jr0rpyOAAyOAAy' ],

}

I have tried :

delete users['115'] == "0ETr8Jr0rpt64nqlAAAF";

Here i want to delete only one value "0ETr8Jr0rpt64nqlAAAF" from 115 key if its exist. How i can do that ?
