[NJTechDiv] copying Zoom invitations

[Mario Brusco]

every Tuesday and Thursday, my sister joins a meeting via Zoom, but the 
invitation does not include the landline phone numbers she can call if 
she is encountering a problem with the computer or the microphone, 
however she can get the numbers from a participant who can copy the 
invitation before the meeting starts. the invitation does include the 
landline phone numbers.
how can I do the same, do I have to be a host? if not, what are the 
steps to copy the invitation?

I also would like to know if there is a setting that the host might not 
be aware of that would include landline phone numbers when the 
invitations are sent? the meeting IDs and passwords are changed every 
Tuesday and Thursday.
