title: How can I set the initial start page in the infinite row model?
body: <p>I'm using the Ag-Grid version 20.0.0 with the Infinite row model and pagination enable. I want to be able to set the initial page for the first load but I don't see any property that allows me to customize that. They only provide the method <code>paginationGoToPage</code> to change the page but this method requires that the grid has been loaded first, and this force me to do two calls, one for the first time (page 0) and the second one to the page that I really want.</p>
