How do you make hyperlink functional on top of an image. or how do you move a text box on top of an image? Just started learning yesterday .Sorry

This is how it looks rn

So as you can see I am able to add text over the the image BUT the paragraph I'm writing has hyperlinks in it, and if I do it the same way as i did the dear .... and the date, the hyperlink wont function at all. So now I am trying to put a text box on the image. But I cant seem to move it where I want it to. I'm making this as a Christmas gift.So I really appreciate any help I can get. Thank you :)
