User Widget UI UMG Responsive to 18.5:9 Mobile Screens and 16:9 Aspect Ratio

I have published my first game on Google Play and when a friend tested it on his smartphone that has an 18.5:9 screen showed me that the UI was narrowed and looking bad.

I realized that I designed the UI based on my 16:9 device, and now I need help making my UI responsive depending on the screen aspect ratio because I can´t find any info on this topic on google.

It would be nice to share here some tips and fixes for the upcoming dev`s.
