My bookings page only show current bookings.

you can try to replace the template file under events-manager/templates/templates/my-bookings.php with this custom my-bookings template – https://pastebin.com/9QxqiDnq

to use templates: https://wp-events-plugin.com/documentation/using-template-files/

eg. wp-content/themes/Your Theme/plugins/events-manager/my-bookings.php

Hello,

Thank you for your message.
It works, thank you very much.
I still have a question: What happens when a plugin update is imported?
Does the existence remain or do I have to do it anew?

if you follow or override EM template with your theme directory, EM will not delete or override your custom templates

e.g. wp-content/themes/Your Theme/plugins/events-manager/my-bookings.php
