Wire-Desktop for Linux missing zoom feature

[jop30]

When switching from Version 3.21 to 3.27 the zoom feature (Menu: Window -> Zoom out) is missing.
This makes it impossible to use Wire-Desktop on small or narrow screens (example: smartphone display with 720x1440 resolution).
On small/narrow displays only the contact list is shown, the actual conversation is missing because it doesn't fit in the window.
The zoom-out feature was the only workaround.
Please reactivate the zoom or make the window scale properly for small / narrow screens.

Edit:
Additional information:

Architecture: ARM64

4. sudo npm install --global yarn
5. yarn
6. yarn start
7. sudo apt install ruby ruby-dev
8. sudo gem install fpm
9. USE_SYSTEM_FPM=true yarn run electron-builder --linux AppImage --arm64

The appear to have removed zoom because of this bug: #5214

[Sven Jost]

The zoom feature had to be removed because of various bugs. But we recently introduced an option to set the font size in the preferences to adjust the app to make the text easier to read.
