Simulate touch_up event in kivy

Question

To simulate a touch_down event I followed the code in this post text

However it does not work for touch_up. it seems that more information must be passed to the mousemotionevent in order for the tocuh_up event to be processed.

Any ideas?

This code can simulate A touch_down event on tab2. But the tabs does not get switched because it does need a touch_up event that I am sending but it does not work.

enter code here

from kivy.clock import Clock
from kivy.core.window import Window
from kivy.lang import Builder
from kivy.uix.floatlayout import FloatLayout
from kivy.input.providers.mouse import MouseMotionEvent

from kivymd.app import MDApp
from kivymd.uix.tab import MDTabsBase

KV = '''

    orientation: "vertical"

    MDTabs:
        id: android_tabs
        on_tab_switch: app.on_tab_switch(*args)


<Tab>:

    MDLabel:
        id: label
        text: "Tab 0"
        halign: "center"
