Is it possible to link a UI element to a gameobject?

Okay, so I've gone through all the links that have been given to me but I'm still struggling. When I attempt to instantiate it, the console tells me I cannot set the parent of a prefab object to prevent data corruption and the 'button' is still invisible. If I drag it directly into the canvas in the hierarchy, then it will reappear immediately.

This is my code, where 'redwizard button' is the button I'm trying to keep near the 'redwizard' sprite: (Also note the final position hasn't been decided, I'm just trying to instantiate it at all, which is why the button would currently be appearing on top of the sprite image)

 public Button redwizardbutton;
 public GameObject redwizard;
 
 void CreateWizard () {
     Vector3 redwizardspawnposition = new Vector3 (
         redwizard.transform.position.x,
         redwizard.transform.position.y,
         0);
     Instantiate (redwizardbutton, redwizardspawnposition, Quaternion.identity);
     redwizardbutton.transform.SetParent (redwizard.transform);
 }

Here's the screenshot with the instantiated object selected (the button should say 'Choose' and appear underneath the red wizard).

Here's a screenshot of where the button actually shows up.

The Quick solution is I think you have to make some a canvas for each like set of the canvas which will instantiate same time when your character instantiated.
