Hi. There is a universal messenger called Rambox: http://rambox.pro/ it is not available in Fedora official repositories ! It is available as AppImage but it will be better if it added to official Fedora repositories ......
This is not the right place to make packaging requests. This is for reviewing packages that a Fedora packager has made to conform with our packaging guidelines and policy for inclusion into the distribution. If you'd like to do this, take a look here: https://fedoraproject.org/wiki/Join_the_package_collection_maintainers
