Add entries as an invited person to a project

My name is Thanos and i have recently started using ragic for organizing a team of 10-15 people. An invited person to the project tried adding entries to our database with survey user rights, however a message to upgrade to lite popped up. So my question is do we need to upgrade to lite as a team so everybody can interact with the project, i.e. adding and modifying entries?
I also attach a screenshot to be clear.


The maximum number of entries allowed on custom sheets when using the free plan is 1000 entries. If you need to add more entries to the sheet, you would need to upgrade your Ragic plan.
