Portal - Display Currency symbol on Web Form

On the portal, we are using an Web Form to display some fields from a custom entity.

On the Web Form step 1 (read-only mode), there is a field that is a currency field, but no currency symbol is being displayed.

Right now, 100$ in CRM displays as 100 on the Portal.

We would like it to be displayed as 100$.

Is there anyway to achieve this with custom javascript? We tried adding the below code to the Web Page and the Web Step Form, but no luck so far.

document.getElementById("new_tarif").innerText = value + "$";

Thanks.
