Width issue of Airtable Calendar embed in List

Hello. I have built a client portal and am slowly but steadily building features into it. I want my clients to see their past and future sessions in an Airtable calendar embedded into a list.

I have tried several lists, and they only cover about 1/3 of the screen. I have width=100% in the iframe.

Is there a way around this on the free plan?

Thank you.

What I ended up doing was manually create the filtered calendar view for each client and save the HTML part the of embed link in a URL field in my CRM table. That link gets mapped to an edit record button that, when clicked, opens a full modular window with the calendar.

I wanted to automate creating the share links with a formula field inserting URL parameters. However, I learned that there is no way to mask them for security purposes.
