I have tried adding it as a class but it seems to need the <i> part of the tag without this though it doesn't render

plz use threadz

the

<i>

tag is not specifically required by FontAwesome; what does the rendered html look like when you do simply add it as a class?

Can you try with the encode attribute:

#linkTo(text='<i class="fa-sharp fa-regular fa-trash"></i>', route="myRoute", encode="attributes")#
