It is just as described above in the thread: they are two different tools. Your understanding of the status is exactly what it is. 
For managing users, you could look into seting up LDAP on both Jitsi and Nextcloud.
Or, setting up Oauth2 from Nextcloud in order for your users to access Jitsi from their nc user account.
I havenāt tried testing how either actually works, but they are possibilities to explore. For further details, check with the Jitsi community.
Hi there!
We are using latest stable NC 20.0.8, and i has not idea how to setup NC talk bot jitsi correctly.

you might forgive me but right now I donāt have the time to read through all comments.
Though I just discovered that thereās a new version of a jitsi-app (beware: youād need your own jitsi-server, though) connecting jitsi and NCā¦
https://apps.nextcloud.com/apps/jitsi
which would eventually solve the threadā¦ 
That is great news. It could be expanded with the old bot framework to simplify inviting users from Talk into Jitsi conferences.
canāt test it myself since I donāt run any jitsi-server 
but you might wanna get in touch with dev directly? checkout his git-page
