I created a custom tab for customer edit page in backend like this:
app/code/Namespace/Module/view/adminhtml/layout/customer_index_edit.xml
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="admin-2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="customer_form">
<block class="Namespace\Module\Block\Adminhtml\Edit\Tab\Vcard" name="customer_edit_tab_vcard" >
<action method="setTabLabel">
<argument name="label" xsi:type="string">V-Card</argument>
</action>
</block>
</referenceBlock>
</body>
</page>
When i opened the customer edit page, the first tab that is active is Customer View
How can i set my custom tab that is active?
