Mobile APP app grid

[chibenwa]

Why

Hint the end user about related apps he can install

For CNB / MU: he shall be advised Twake Sync

For Linagora: Twake Sync, Twake chat and why not LinShare

For TWP: Twake chat

=> We see that this app grid is deployment dependant

So this means the back needs to be configured for it, and info carried over to the front.

What

Add a section in /.well-known/linagora-ecosystem:

"mobileApps": {
    "Twake Chat": {
        "logoURL": "https://xyz",
        "appId": "abc"
    },
    "Twake Drive": {
        "logoURL": "https://xyz",
        "webLink": "https://tdrive.linagora.com"
    },
    ...
}

Should be configurable...
