Get order_id in UI Component GRID in a new Sales View Tab

After a lot of tries, I couldn’t manage to get an order_id to a Admin Grid Dataprovider.

This is the code I have

view/adminhtml/layout/sales_order_view.xml – To add a new tab to order view

<?xml version="1.0"?>     <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>             <referenceContainer name="left">                 <referenceBlock name="sales_order_tabs">                     <block class="Invoicing\Moloni\Block\Adminhtml\Order\View\Tab\Documents" name="sales_order_documents.grid.container"/>                     <action method="addTabAfter">                         <argument name="name" xsi:type="string">moloni_documents</argument>                         <argument name="block" xsi:type="string">sales_order_documents.grid.container</argument>                         <argument name="after" xsi:type="string">order_invoices</argument>                     </action>                 </referenceBlock>             </referenceContainer>             <referenceBlock name="sales_order_documents.grid.container">                 <uiComponent name="orders_documents_grid"/>             </referenceBlock>         </body>     </page>

Whenever I try to open the sales order view, all other tabs load the url like this:

https://magento.retronwarz.com/admin/mui/index/render/key/0d7cba1af800b031dce791267facdc34b5a062f3932738f45e74225339a629e8/order_id/8/?namespace=sales_order_view_invoice_grid 

But, when I try to load my tab, the param order_id is not sent, so it looks like:

https://magento.retronwarz.com/admin/mui/index/render/key/0d7cba1af800b031dce791267facdc34b5a062f3932738f45e74225339a629e8/?namespace=orders_documents_grid&isAjax=true 

Does anyone know how I can overcome this and send the order_id to the tab URL?
