Implement Google Map with iframe and Navigation Button doesn't work


I i have create some maps with google my map and i had put them on the ionic application.
Although the navigation buttons don’t work when i run it on android device. It work on browser.
At the below image you can see which button i am refer to. Now if i click it, it doesn’t do anything

The code that i have for the map is this iframe

<iframe src="" zoom="10" width="100%" height="100%"></iframe>

Any thoughts?
