I am trying to use the Flutter SelectableText Widget to make sure it is possible to copy the Text in my web application, but there is no 'copy' option appearing in the Context Menu.

I am using the following Code ("select all" and "copy" should be given as default toolbar options https://api.flutter.dev/flutter/material/SelectableText/toolbarOptions.html):
SelectableText(
'Hello from Flutter',
),
Can anyone help me with this problem?
