How can I display chat widget on mobile without affecting other artifacts?

I want to know a best way to display user chat icons on mobile, as these widgets are overlapping with other artifacts of screen. In mobile due to lack of space, overlapping of icons is appearing. What should I do to prevent this issue? Where and how should I place these chat icons for mobile display? Will it be nice to display these icons in a minimized way in right side of screen? Using this, these icons might appear when user click on that minimized sign. Please suggest best way to display these. Sorry for bad English.
