magento2 – Import Product Programmatically

For product import,

I used to create a CSV file from the text file (from customer) via programming. Then I place it in var/import folder

Now, For Magento 1.9

My code was :

$profile = Mage::getModel('dataflow/profile');
$profile->load(7);  (7 for products)
$profile->run();

My all product are imported successfully.

The same way Now I am trying for Magento 2.3

I have successfully created CSV file from the text file (from customer) via programming.
Also from Admin > System > Data transfer > Scheduled import/export > New Scheduled Import
I have created one “scheduled import” for product.

Now, Please help me, how can I run it via programming. like ($profile->run();)

Thanks in advance
