Re: "I’m trying to turn on guided access on an iPad mini : How can I use guided access? "
Apple support's online article (link below) may be helpful:
How to: Use Guided Access with iPhone, iPad, and iPod touch - Apple Support
Eg: says how to:
Set up Guided Access
- Go to Settings > Accessibility, then turn on Guided Access.
- Tap Passcode Settings, then tap Set Guided Access Passcode.
- Enter a passcode, then re-enter it. From here, you can also turn on Face ID or Touch ID as a way to end a Guided Access session.

There is much more info. in the above article that can guide you:
Eg: says
"End a Guided Access session
Triple-click the Side or Home button, enter your Guided Access passcode, then tap End.
Or if you turned on Touch ID or Face ID for Guided Access, double-click the Side or Home button".
