We could use an AppleScript like this for Chrome. I modified this simple script: https://github.com/mobjack/MacChromeCalendarFocus
Still having a little trouble focusing the correct window. If anyone can help on that please let me know what's missing:
tell application "Google Chrome"
repeat with w in windows
set i to 1
repeat with t in tabs of w
if URL of t starts with "https://inbox.google.com/" then
set active tab index of w to i
set index of w to 1
tell application "Google Chrome" to activate
tell application "System Events"
keystroke "c"
end tell
return
end if
set i to i + 1
end repeat
end repeat
open location "https://inbox.google.com/"
tell application "System Events"
keystroke "c"
end tell
end tell
tell application "Google Chrome" to activate
