Share LTE connection via Tmobile tm-ac1900 router? topic

I'm between Internet providers at my house. I have the Tmobile tm-ac1900 router (the one made by asus).

Is it possible to somehow share my phones LTE connection thru the router to my LAN?

I thought that was an option of the router but I can't figure it out.

I hope this questions reads clearly.

Basic terms: house Internet is out, I want to use my phone LTE connection to supply Internet to my LAN through the router... So I would assume connect my phones wifi tethering somehow to the router as the WAN so it would supply Internet to my hardwired devices to the router.

Thanks in advance.
