Hello Darya,
Thanks for posting this question to us.
This functionality isn't possible in the Prismic. But I understand how it can be useful to overview all the titles and descriptions from all the articles in one place. I am going to add this as a feature request for future improvements.
There can be a workaround to do this via the API. For example, one of my team member set up a Custom function in Google sheets to get document titles from Prismic. You can try to do this with SEO titles and descriptions.
I hope it works well for you.
Thanks,
Priyanka
