I have added a button in the EventInfo.tpl
<div class="crm-submit-buttons">
<div style="display:none">{include file="CRM/common/formButtons.tpl" location="bottom"}</div>
<span class="approved-logic crm-button crm-button-type-upload">
<button>Approve</button>
</span>
<span class="request-approval crm-button crm-button-type-upload"
<button>Request for Approval</button>
</div>
But when I click on Add Event under Manage Events, I see a popup which does not
show my button but when I click on add event and add it to new window it shows
the button, how can I make sure it works on both the places
1) Popup
2) New Window(which is showing currently)
