I'm still not get it how to mix/blend soldier character weapon aiming animation with walking animation ?

What i did so far:

1. Created new animator controller for my third person character.

2. Created a From New Blend Tree called it Movement and i did a Transition from the Entry to the Movement.

3. Created a new State called it Aiming and assigned in as motion Rifle_Aiming_Idle

4. Created two transitions from Movement to Aiming and from Aiming to Movement. From movement to aiming the conditions: Aiming True and from aiming to movement the conditions are: Aiming False.

5. Inside the Movement blend tree i added two new motions: HumanoidIdle and Rifle_Aiming_Walk_F_RM

6. Added parametersL Velx,Vely both float and also parameter name Aiming bool.

7. HumanoidIdle set to 0 and 0 and Rifle_Aiming_Walk_F_RM is set to 0 and 1.

Then i attached to the character this script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Soldier : MonoBehaviour
 {
     private Animator anim;
     private bool aim = false;
     
     private void Start()
     {
         anim = GetComponent<Animator>();
     }
 
     void Update()
     {
         var inputVelx = Input.GetAxis("Horizontal");
         var inputVely = Input.GetAxis("Vertical");
 
         transform.Rotate(0, inputVelx, 0);
 
         anim.SetFloat("VelX", inputVelx);
         anim.SetFloat("VelY", inputVely);
 
         if (aim == true)
         {
             anim.SetBool("Aiming", true);
             anim.SetFloat("VelX", inputVelx);
             anim.SetFloat("VelY", inputVely);
         }
 
         if (Input.GetMouseButtonDown(1))
         {
             anim.SetBool("Aiming", !anim.GetBool("Aiming"));
         }
     }
 
     private void FootStep()
     {
         
     }
 }
 

And the results:

When running the game the character start in idle state. When i press the W key the character is walking forward and also aiming at the same time. When i leave the W key the character is back to idle state without aiming.

If i click the mouse right button the character will aiming but will stay in aiming idle state if i press now W he will not move.

My main goal is how to make that when i click the mouse right button it will aiming and also when pressing W will walk. Now it's only aiming but when i press W it's not walking.

Screenshots:

The first is the parameters with the main layer: On the right you can see the state Aiming with that i'm doing the right mouse button click to get to aiming state and this is where i also want to make that if i press W it will also walk.

The second screenshot show the blend tree mixing the idle with the walking this part is working fine:

In other words i want to make that right mouse click i'm in aiming idle state and if i will press then the W key it will start walking if i leave the W key he will back to aiming idle state.
