Cisco Webex - Lazarus IDE - R installation

Hello!

I would like to ask you if it would be possible to install Cisco Webex successfully and how? Unfortunately I have seen that in Endless App Center there is no such application option, but they have released distribution (.deb) in their download’s page (https://www.webex.com/downloads.html)

Additionally if it would be possible to install and uninstall Lazarus IDE via the following commands for Ubuntu.

Finally if it would be possible to install R & Rstudio via the following tutorial for Ubuntu.

Regards
