Same Android smartphone as hotspot and connected device to same itself hotspot. is it possible?

Hi folks! I'm newbie here and I've a big problem that I hope someone can help me to solve it!
I need to use my android smartphone as hotspot, sharing my mobile internet to connected devices but at same time I need to use same smartphone also to connect it, as WiFi, to the same hotspot!!
Why?
Because I've some device (eg. Oculus Quest VR and clean robot) whose apps need (force!!) to have connected Android smartphone where the app is installed, to the same WiFi network of the device!
Eg. I'd like to cast my Oculus on the app that I've installed in my android smartphone or I want use my clean robot throw the app installed, again, in my android smartphone but I can't because those apps don't see my smartphone connected to same WiFi network (of course!! My smartphone is hotspot to allow those apps to use internet and be devices connected to same network!! So how could my smartphone be also a WiFi Android device connected to itself??)
So, if I use my smartphone as hotspot, I can't use it also as WiFi connected device to the same hotspot!
I know, is tricky but I really need it because I don't have a typical home internet so I only use my mobile internet in hotspot throw my android smartphone. So I don't want pay for to buy an extra, new, device hotspot and new internet connection just because some app force me to use itself with the device(Oculus VR, clean robot..) only into same WiFi network with internet!!
I also tried to use a second Android smartphone (without second SIM card with internet, just the phone) with netshare app installed on it but I'd share internet from my primary Android to netshare and also connect my primary Android to WiFi to secondary device to satisfy app needs. I tried it but I didn't able to share internet.
It's creepy!
Is there a way?
Please help me
Thank you
