How to insert an argument into an attribute value in a pug mixin?

Question

Pug

Here is a mixin that doesn't compile. You just need to insert the src of the image in style.
I tried without brackets and without a lattice - it's useless ... How is this done correctly?

mixin team(img_src)
  span.team-card__photo(style="background-image: url("=#{img_src}");")

Answer 1

mixin team(img_src)
    span.team-card__photo(style=`background-image: url(${img_src})`)

Answer 2

shape-rendering="crispEdges"
