Building a simple email client with Adalo and Gmail API?

Hi all - I’m trying to evaluate whether Adalo may be a good fit for our project and would appreciate any insights.

We have a design for a simple feed (see here https://www.returnofthenewsletter.com/prototype) but would need to utilize the Gmail API to recognize newsletters in the user’s inbox that we’d then display in our reader app.

Essentially, it can be compared to a simple email reading client.

Does anyone have any experience with this?

At the moment, I’m not sure this would be possible as I believe you would need your users to authenticate their Google credentials through oAuth, which we don’t have yet.
