        isSuccessful = putFileContentRes.isSuccessful();
    } catch (Exception e) {
        LOGGER.error(WOPIConstants.EXCEPTION_WOPISERVICE_POSTFILE + e);
    }
    return isSuccessful;
}

Using springfox-swagger2 and springfox-swagger-ui Version : 2.9.2

Above mentioned is my code of a rest service which accepts a file in request body. Is there a way in Swagger UI to get fileupload button
In postman I was able to send file in the following way

In swagger Ui it is coming like this

Is there a way that I can annotate to determine that requestbody is a byte array of a file so that I can get File upload button in Swagger UI
