Suspicious link with a dot

[AtLeastMaybe]

https://us05web.zoom.us/j/<conference id>?pwd=<password>.1


Greetings, i have had this type (in such format) of a link on a meeting.

I know that us05web.zoom.us is normal thing. But this ".1" seem unreasonable. Especially a fact, that i can enter the conference without that fragment.

Can URL schemes and post-attendee be used for malicious attacks? And what is their type? Especially if someone knows my network data (IP, etc).
