LG webOS , stream video content

I would like to store videos and photos on my home assistant system (Raspberry PI 4 and 1TB SSD.) then be able to see them on my LG webOS smart tv.
Is there any way to get this working ?

you can install some apps into tv (i am using fire stick and installed something called media center) and it allows me to cast into it, as if it is google cast enabled.

Not sure, if lg app store has a similar functionality
