I tested this PR and it is working as expected (I had to merge the main into the branch due to errors in the entity lookup modal)

The translations inside the lookup modal in relation to DataSet are missing.

Thanks @mahnkong for the test. I rebased the branch on the main branch and added the missing i18n tags.

Some translations are still missing. Inside dataset submission, when relating other entities (Author, Publication)

Example for Author:

submission.sections.describe.relationship-lookup.title.isAuthorOfDataset
submission.sections.describe.relationship-lookup.search-tab.tab-title.isAuthorOfDataset

Hi @mahnkong ,
thanks! Sorry, I missed those. I added the i18n tags and corrected an additional error, where I had put the wrong metadata field label.
