Problem with form on export

we need put code of form from third-party but doesnt understand how to do that

< script >var amo_forms_params = {“id”:335503,“hash”:“4427b8b3bea8d94c8a3f99ce44a19a73”,“locale”:“ru”};< /scrip t>< script id=“amoforms_script” async=“async” charset=“utf-8” src=“”>< /script >

we have code like rhat but when we put this code in website its bring their form with their design but we need our form-design… how we can solve that?
