Openwrt portal captive with sms otp

Installing and Using OpenWrt
1

Dear all
I bought GL.iNet GL-MT3000 (Beryl AX) Pocket-Sized Wi-Fi 6 Wireless Travel Gigabit Router with pre-install openwrt and I'm using NETGEAR Nighthawk M6 Pro Mobile Hotspot 5G mmWave connected to GL.iNet via tethering.

I want to install portal captive support sms otp so no one can connect to GL.iNet wifi without put his mobile number to get otp code from sms
I hope it's clear and I need your advice please
with regards

Are you running the GL-inet vendor firmware or have you installed official OpenWrt?
What is the output of:

That firmware is the gl-inet fork...

If you are going to continue to run that version, you need to ask on the gl-inet forums since their fork is materially different than the official OpenWrt.

Alternatively, you can install official OpenWrt -- your device is indeed supported. We can help you here if you are running the official version.
