Dolphin Advanced Emulators Launcher Kodi command line won't work

[Myghalloween]

Good morning all
I am desperately trying to launch Dolphin on my Shield TV pro from Kodi thanks to Advaced Emulators Launcher but without success. Dolphin works fine but when I try to create a rom launcher nothing happens. Others emulators works well with the same type of command.
Here is my command line:

<application>/system/bin/am</application>
<args>start --user 0 -n org.dolphinemu.dolphinemu/org.dolphinemu.dolphinemu.ui.main.MainActivity -a android.intent.category.LAUNCHER /b /e "%rom%"</args>

Did any of you succeed?
Thanks for help
