App shows in launcher after 15s delay

I’m seeing this weird issue where app shows in launcher after 15 second delay. How can I figure out who is causing this: app, electron or gnome-3-28 extension?

name: typora
...
    command: wrapper $SNAP/typora/Typora --no-sandbox
    extensions: [gnome-3-28]
...

What makes it weird is that launching from terminal typora or snap run typora it shows instantly. When started from app selection (Show Applications) or file selection (Files) it delays.
