Algolia Not Updating After Adding New Products to Magento

I have Magento 1.9.
I have done the initial product update and it worked absolutely fine. I have noticed any new products added to my Magento today are not appearing in the search index. I have tried the search index from my algolia console and the new products are not there.

Any idea what I need to configure to upload new products in the algolia index.

Can anyone help me with this?
