Hi Manuel,
Thanks for posting back.
According to your reply, you are using the new Forms feature in the list, not a form from Microsoft Forms.
If so, please note that they are different features, and the form created by the new Forms feature is not a Microsoft form. In this case, you used the wrong trigger "When a new response is submitted" and the wrong action "Get response details" in your flow. Instead, you should use the trigger "When an item is created" and the action "Get item".
Also, for the employee's manager, you can use the action "Get Manager" and add "Created By Email" from "Get Item". For HR and VP, you can add their email address in the action "Send an email" or use the action "Search for users" and then add "Email" from it in "Send an email".
For the comments, you can use "Responses Comments" from "Start and wait for an approval" in "Send an email".

We look forward to your response. Thanks for your cooperation.
Sincerely,
