I hope I did everything correct. It's my first time using git.

Edit: You motivated me to add a few more. For Riot.im I was not sure how thin a line can be. Therefore I created to different ones, just choose one and rename it to "riot.svg". Btw. what is the rule for the apps. To be available on f-droid is not the cause because you also included the LOS apps. I'm wondering if it would be possible to include e.g. the browser app of carbonROM, or Wire.
