Not working meeting SDK footer buttons

[user3]

I am creating a vue.js app to host zoom meetings on the web using the Meeting SDK.
However, I am experiencing a phenomenon where the footer button disappears depending on the width of the zoom function screen being invoked.

As I gradually shrink the width of the screen, the buttons disappear in the following order

1Chat
2Participant
3Share screen
4Security

The microphone, camera, and "further information" remain until the end, but "further information" does not respond when clicked, making it unusable in the first place.

Crucially, when you click on a participant, the "Participant" button disappears and the right side participant menu cannot be hidden.
Once I click on the "Participants" button, the side menu stays open forever.

Please let me know how to solve this problem.
