Can we modify "Send Alerts To " field to add/remove users from existing alerts

Question

I have created an alert and i defined 3 users (including myself) to receive the alerts:-

but after creating the alerts I noticed the following 2 issues:

1. if I edit the alert I can not add/remove users from the "Send alerts to" field.

2. also if I remove the alert from my user, it will not remove them from the 2 users' alerts

is this how alerts work?

Thanks

When you click on "Manage my alerts" from SharePoint list, it will only show your alerts on the SharePoint site:

https://contoso.sharepoint.com/sites/siteName/_layouts/15/mysubs.aspx

If you are site admin and you want to delete alerts for other users, follow this:

1. Go to Site Settings page
2. Select "User alerts" under "Site Administration" (https://contoso.sharepoint.com/sites/siteName/_layouts/15/sitesubs.aspx)
3. To select a user, select Display alerts for, and then select Update.
4. Next to the alert you want to delete, select the checkbox, and then select Delete Selected Alerts.
5. Select OK.
