zoom app vs. zoom web client

[mdkzooom]

My wife and I work on separate computers.  I have a paid zoom subscription, she does not.  Recently, we both received a meeting invite from an outside source and wanted to attend the same meeting.  WIth the full featured zoom app (which is installed on both of our machines) it would only let ONE of us log in at a time.  I tried to use the web client option using Chrome browser, but it always wanted to default to the installed zoom app, and bounced me off.  We just want to be able to go back to using the free web client, so how do we work around this?  I do not want to un-install the app. form our machines though.
