Quick Hotspot is the best way to share your WiFi connection with your friends. It works with Wi-Fi, not 3G/4G/5G. You don't need to install anything else, just download this app and you are ready to go. You will need to enter the password of your WiFi network and the name of the network, then the app would generate a new password for you. This app works in two ways: with and without mobile data.

With mobile data, you need to enter the data of your phone, but without data, it would not work. If you do not input anything, it would automatically generate a random password for you.
