Editing schedule times when registration open

[ZLS]

I am working on hosting a +2000 audience webinar. We have integrated Zoom with Hubspot, so all registrants receive a personalised link to join the webinar on the day via our Hubspot flow. We don't send any registrant emails via Zoom.

I would like to extend the scheduled time for my webinar by +30 minutes just to give more buffer and to avoid any potential that we pass the scheduled end time and the webinar automatically shuts off (I understand that this shouldn't happen but sometimes seems too... from what I've read in the community here).

My question is - if I edit the scheduled time of my webinar, will this impact the registration flow/links? Note, we don't send registration emails/confirmations via Zoom, but rather through our Hubspot integration. 

Thank you!
