Hi Imran,
In the Apple Appstore, you will find a glTF viewer. It is for free.
(I can’t give support for this, nor promise anything, as it is a 3rd party app.)
Export your model and send it as an attachment to yourself.
To open it it will prompt you to choose.
Use the glTF viewer and place it.
Android version, no experience so far.
That’s all.
More about the export and some other tips.

Enjoy.
