Hi Muhammad,

You need to create a lightning component that implements force: lightningQuickAction. After this, you will be able to override your Action using this lightning component. You can program your client-side controller to set a callback function, that would call your Apex class to perform some logical calculation. This is fairly simple and you can find numerous example on the trailhead.

var action = cmp.get("c.YourMethodName");
action.setParams({
     param1: cmp.get("v.something1"),
     param2: cmp.get("v.something2")
});
action.setCallback(this, function(response) {
   if (response.state === "SUCCESS"){
       var serverResponse = response.getReturnValue();
   }    
});
$A.enqueueAction(action);

Check out this link:

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
Thanks,

Hi,
You can use below code first to create a component 

Component  
<aura:component implements="force:lightningQuickAction,force:hasRecordId,force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome" controller="BatchApexController" >
	<aura:handler name="init" value="{!this}" action="{!c.myAction}"/>	
</aura:component>

JS Controller 
({
	myAction : function(component, event, helper) {
		var action = cmp.get("c.callBatch");		
		action.setCallback(this, function(response) {
   		
        if (response.state === "SUCCESS"){
        	var serverResponse = response.getReturnValue();
   		}
            
		});
		$A.enqueueAction(action);	
	}
})

Once this is done, Follow the below step
  1. Go To the Object Definition page
  2. Click on Button, Links and Action
  3. Click on New Action
  4. In Action Type Select Lightning Component
  5. Select the component Which you had just created
  6. Fill other Mandatory fields and Save
  7. Add Quick Action to Page Layout by editing Page Layout
