It sounds like you need help with the Shortcuts app which is separate from Notes.
Once you've opened the Shortcuts app, look for a plus sign to create your own shortcut. There will be a field that asks to Search Actions. Enter Notes there for a list of actions you can use in Notes, the action you want is Show Notes Folder. Select it to add that action to your shortcut, then click on the highlighted word Notes for a list of your folders and smart folders. Select the folder you want to show. Give your new shortcut the name you want to use in links from your notes.
