Here is documentation about Add Lightning Components as Custom Tabs in Lightning Experience.
https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/aura_add_cmp_lex.htm
However, when I add as above, I can see the tab only when I open App louncher, then select our app. Actually, it is added to app launcher as an app. Than I can see and select tab there.
I want my component's tab is shown in all apps, no matter what I choose from App Launcher.
Is it possible?
NOTE: I also should set some attributes of my component to work properly. But adding it according to documentation, I cannot set attributes.
