name 'QtGui' is not defined

When I chose "shapefile" instead of "memory", and trying to locate a file, the plugin crashes :

NameError: name 'QtGui' is not defined
Traceback (most recent call last):
File "/home/ben/.local/share/QGIS/QGIS3/profiles/default/python/plugins/Beeline/beeline_dialog.py", line 47, in browse
fileName0 = QtGui.QFileDialog.getSaveFileName(self, 'Save as', self.oldPath, "Shapefile (.shp);;All files ()")
NameError: name 'QtGui' is not defined
