Approval Flow Based on Approval level

[Workflow123]

Hi, I have developed a workflow for functional head, head, and EHS approval. I must now modify the workflow to meet customer requests before it can be executed. now the approval should be done based on  the approval level mentioned Here is an example of a Approval level: if Approval level 2 is specified, the Approval should continue until the specified Approval level is reached, at which point the approval should be sent to the first and second users. In the same way that we wish to develop a flow for infinite approver level, if IT 4 mentioned it, the workflow should continue until the fourth approver.

so what condition we apply..

can someone please help to clear this or suggest some solution.

Hopefully I can explain this so it makes sense.

1. Set up one workflow for each of the approvals. Based on image 6, it looks like you have a max of four approvals.
2. Assuming the approvals go in order and approval 1 is always required, that workflow will run when the item is created.
3. When you get the response back from approval 1, if it has been rejected, then that ends the approvals. If it has been approved, then call your second approval workflow. 
   1. You can call the second workflow a couple of different ways. You can create a child flow, which you will then need to set up your approvals in a solution. This will limit your entire approval process to 30 days. The other method you can use is the trigger action When a HTTP request is received. The prior flow will call the next flow with an HTTP request, and it will pass the ID of the first flow to the next flow so you can use the Get item action to get the details of the original request. It will also need to pass the approval level needed. This will allow you 30 days for each approval and is the method I use.
4. Then in the workflow that is being called, add a condition to check if the approval level is needed. For example, in the flow for the second approval, you would add a condition to check is approval level less than or equal to 2. If so, the flow will send the second approval. If not, then the approvals are done and the request is approved.
5. You would then repeat this process for the remaining approvals passing the original item ID and approval level to each flow that is called. 

You could do this all-in-one flow as well if you know the entire approval process will take less than 30 days. After each approval (if it has been approved) add a condition to check if the approval level is less than or equal to that approvals level in the flow. If it is, on the yes side do the next approval. The no side would indicate no additional approvals are needed.
