how to share images and aligned text to what's app programmatically

I am currently working on below requirements in asp.net core 3.1,
My output,

When User clicks on Whatsapp button the respective description and its images need to be shared in what's app. Currently, I am using https://api.whatsapp.com/send?text= this api to share the description. As you can see below image,

Till above everything works fine. Here I have two questions,
1.)is there any possible way to share images to what's app using same or different api?
2.)The content which is shared is need to be aligned. Say for egg,
If I am adding description like below,
aaaa
bbbd
cccc
it need to be share exactly as above. But currently it is sharing as in one line string, like aaabbbdcccc. Any possible way for sharing aligned text?
Please help.
Thanks.
