Solved Notification icon from local file

Hi, I'm a new Join user and this app is awesome!
I'm still testing it to see if it can completely replace my notification system and I'm facing some issues: I want to send notifications with a custom icon, if I put an icon in png format from my gdrive, the notification shows the icon, if I try to set a notification icon from a local ressource it's not working.

The concerned icon is exactly the same, it is stored on my NAS and on GDrive. I'm running curl from my NAS with the following command :
curl 'https://joinjoaomgcd.appspot.com/_a...'group'&title='TITLE'&text='TEXT'&icon='$ICON
$ICON is set with the following commands :
Web : --> WORKING
ICON=$(urlencode "https://lh4.googleusercontent.com/4...zUrxSulpwzF4nqUkOSBBQ2ekIkUpKNHuw=w1920-h1069")
Local : --> NOT WORKING
ICON=$(urlencode "file://***full path to***/flex.png")

Am I using file URI in a bad way? Can you help me with that?

 

Hi and thanks for your help, when I say local I mean on the NAS, is it possible that way or does the icon needs to be on the phone?

 

Ok, I thought it had to be on the device used to send the notification, I'll try to put the icons on my phone and report here!

EDIT : it works fine on the phone, not on the other device (I guess because the icon is not accessible), is it normal? The only way to have icons on all devices is to use an icon from the web?

 

So, I uploaded my icons to a personal server, I'm still sending pushes from my NAS and I can see the icon(s) on my mobile but not on my computers with chrome addon, the standard Join icon is showing in the chrome desktop notification, not the custom icon I've set (the custom icon is showing in the notification section of the chrome addon). Is it normal behavior?

 

Alright, thanks a lot! I'll try to do that!
