Change the shape of a QLabel - pyqt5

Question

I would like a little help, I am trying to generate a chat room but I would like that the QLabel that I use to show the messages had the form of a message container like this
And not only with the typical square shape of a QLabel
I tried to do the following:
def CreateLabel(self):
image = QtGui.QPixmap("container.png")
mask = image.createMaskFromColor(QtCore.Qt.red)
self.Label = QLabel()
self.Label.setText("Test Text")
self.Label.setAlignment(QtCore.Qt.AlignRight)
self.Label.setMask(mask)

Answer 1

Try it:
import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
class Label(QLabel):
def __init__(self, text):
super().__init__()
self.text = text
self.im = QImage('D:/_Qt/img/chat.png')
self.resize(self.im.size())
def paintEvent(self, event):
super().paintEvent(event)
p = QPainter(self)
p.drawImage(0, 0, self.im)
self.drawText(event, p)
def drawText(self, event, p):
p.setPen(QColor(168, 34, 4))
p.setFont(QFont('Decorative', 12))
p.drawText(event.rect(), Qt.AlignTop, self.text)
def closeEvent(self, event):
quit()
class Widget(QWidget):
def __init__(self):
super().__init__()
self.text = """
