Multipurpose buttons

As in the title, I am trying to figure out how to use a button for multiple purposes in Unity.

In my specific case for instance, I am currently using the joystick button 0 (the A button) to perform a simple melee attack:

if (Input.GetButtonDown("Fire1") && currentState != PlayerState.attack && currentState != PlayerState.stagger) 
//second clause because I do not want to indefinitely attack every frame
{
    StartCoroutine(GetComponent<Player_Melee>().FirstAttack());                    
}

In the conditions I make sure that I am pressing the right button and determining in which state my player is (the state is then changed in the attack coroutine). In order to interact with a given object, I created a trigger to check that the player is within range to inspect the object:

if (Input.GetButtonDown("Interact_Alt") && playerInRange)
{
    if (dialogueBox.activeInHierarchy)
    {
        dialogueBox.SetActive(false);
    }
    else
    {
        dialogueBox.SetActive(true);
        dialText.text = dialogue;
    }
}

In the Input manager settings in unity, I set the 'Interact_Alt' button to be the same as the 'Fire1' used in the attack script. The scripts actually work, however whenever I check an object I also perform an attack. How can i make so that when I want to inspect an object I do not attack?

I was considering create a new finite state similarly to the one I use to attack e.g. 'PlayerState.interact', but then I was wondering, how would unity give the priority to which command to use?

Another alternative would be to check if I am in the range of some object when I want to attack and if within range it inspects the object instead, but it seems to me a much more convoluted solutions.

How should I solve this?
