Project not allowed to use a database

What are you trying to do? (please be as specific as possible and include relevant screenshots, code snippets)

I am using a database which has been used in the project before and getting the following error

What are the reproduction steps?

Hi, if you have enough permissions to access/execute data operations in the data source, you should be able to “allow” the data source into the project by creating a new data operation with the data source. From what I can see in the image the integration picker seems disabled, so it may be the case that you don’t have enough permissions.
