Smart-user-Picker in cutom UI Forge APP 403 (Forbidden)

Hi there,

I’m developing a Forge App as a custom-ui Confluence macro. I wanna use the atlaskit smart-user-picker component but I’m getting this error when typing in the field:

https://ea258da26d824e9cae66faff27da8aba.cdn.prod.atlassiandev.net/gateway/api/v1/recommendations. 403 (Forbidden)

This is how I’m using the component:

    <IntlProvider locale="en">
      <SmartUserPicker
        fieldId="example"
        name="Approvers"
        baseUrl='myname.atlassian.net'
        siteId='2323'
        productKey='confluence'
      />
    </IntlProvider>

with siteId beeing the one from myname.atlassian.net/_edge/tenant_info.

Am I missing somehting ? or is this not supposed to work at all ?

Thanks.
