like this:

   //i'm assuming you're setting this in the editor
   var myTag : String;
        
        
   function OnTriggerEnter(col : Collider){
         //get the object of the collider we just hit
         var obj : gameObject = col.gameObject;
         
         //compare it's tag to the one we want
         if(obj.tag == myTag){
         doThings();
         }
    }

On the object with the collider make sure “is trigger” is checked in the inspector. Then attach a script that has the function OnTriggerEnter(). Inside this function you would do the IF statements to check if the tag is player of the entering collider.
