How to make such a block using flex?

Question

HTML

I need to make such a block using flex, but there is a problem with the line in the middle:
It should be long and separate two blocks of text, but it reaches the edges of the padding top and bottom, and I need it to go beyond these edges, how to do this? Because when you change the paddings, the size of the image itself changes and the blocks themselves on the right and left

How the block should look


How it turned out for me


The code itself, but I don’t know how to add the placeholder, I registered the dimensions of the backgrand, please help!
