Welcome to the Zoom Community, @menton95.
The reports are available to the meeting host from the Webinars menu:

Once there: In Step 1: Select Report Type, click the Registration Report radio button. In Step 2: Choose a Webinar, enter the appropriate dates in the date fields or enter the webinar ID, and once the desired webinar is found, click the radio button on the far left. Then in Step 3: Generate the Report, click the blue Generate CSV Report button.

Your report will be downloaded to your browser's Download folder. Open with Excel or any other CSV reading program. I created one custom question, "Are you a member?". The answer is highlighted.
