Questions Regarding Free Version Features and Limitations

Hello, I have the following questions:

1. Will the free version include a watermark?
2. Does the free version allow filtering by language and rating stars? (Since our company receives reviews in various languages, we may need to filter out specific languages e.g., Chinese)
3. How many widgets can be placed on the same domain with the free version?

We would like to test it first before purchasing the paid version to apply across multiple domains.
