Normie4,
From that same resource, you can use the following guidance to connect to that established Hotspot connection:
"Wi-Fi
On the device that you want to connect to, go to Settings > Cellular > Personal Hotspot or Settings > Personal Hotspot and make sure that it's on. Then verify the Wi-Fi password and name of the phone. Stay on this screen until you’ve connected your other device to the Wi-Fi network.
On the device that you want to connect, go to Settings > Wi-Fi and look for your iPhone or iPad in the list. Then tap the Wi-Fi network to join. If asked, enter the password for your Personal Hotspot."

"Use these steps first
Try connecting again after each step.
- Check that Personal Hotspot is turned on in Settings > Personal Hotspot. If you can't find or turn on Personal Hotspot, check that your wireless carrier enabled it and that your wireless plan supports it.
- Restart the iPhone or iPad that provides Personal Hotspot and the other device that needs to connect to Personal Hotspot.
- Make sure that you have the latest version of iOS or iPadOS.
- On the iPhone or iPad that provides Personal Hotspot, go to Settings > General > Transfer or Reset [Device] > Reset, then tap Reset Network Settings.
Use the steps below for more help with Personal Hotspot over Wi-Fi, USB, or Bluetooth.
If you can't connect to Personal Hotspot with Wi-Fi
On the device that provides Personal Hotspot, go to Settings > Personal Hotspot, then follow these steps:
- Make sure that Allow Others to Join is on.
- Remember the device's Wi-Fi network name and password that appear on this screen. If you want to change the Wi-Fi network name, learn how to change your device name.
- If you're using an iPhone 12 model or later, turn on Maximize Compatibility.* Then try connecting your devices again to your Personal Hotspot.
- Stay on this screen until you connect your other device to the Wi-Fi network.
On the device that needs to connect to Personal Hotspot, follow these steps:
- Turn Wi-Fi off and back on.
- Make sure that you connect to the correct Wi-Fi network. The network name is the same as the iOS device that provides Personal Hotspot and the Personal Hotspot icon
might appear next to it. - If you see a password error when you try to join Personal Hotspot, check the Wi-Fi password: On the device that provides Personal Hotspot, go to Settings > Personal Hotspot to see the Wi-Fi password.
* When you turn on Maximize Compatibility, internet performance and Wi-Fi security might be reduced for devices connected to the hotspot."
Cheers.
