How to get line item id in the return of checkoutLineItemsAdd mutation?

@Luke_K

Is there any way to get the line item id from the checkout object in the liquid file? Actually, I got one using this link

https://shopify.dev/api/liquid/objects/line_item

And I tried to encode it to base 64 code.

gid://shopify/LineItem/******** → base64 code

But it is saying invalid id. Do you have any idea about this?
