How to send media files on whatsapp programmatically using click to chat feature?

Question

I have to use whatsapp's click to chat feature for automating the process of sending messages to unsaved numbers. I am currently using selenium to automate the process. I am able to send text messages only for now. I was wondering that it might be possible to send other media files as well like images and videos.

There are 2 unused parameters in my url of click to chat feature, "source" and "data". I thought using these might enable me to send media files but I Haven't been able to do it yet. Example URL for one of my click to chat messages:

https://web.whatsapp.com/send?phone=phoneNumHere&text=Hi&source=&data=

Can anyone confirm that either its possible or not. If its possible what would be the right way to do it?

Thanks

Send images, videos and docs using Selenium:

//To send attachments
//click to add
driver.findElement(By.cssSelector("span[data-icon='clip']")).click();

//add file path
driver.findElement(By.cssSelector("input[type='file']")).sendKeys("FilePath");

//click to send
driver.findElement(By.cssSelector("span[data-icon='send-light']")).click();
