How to setup a connector for outlook and microsoft teams?

i'm building a connector for MS Teams and Outlook. I have registered the connector on Connectors Developer Dashboard but when I sideload it on outlook and I try to configure the connector... Nothing happens in my setup page. Indeed,

microsoftTeams.settings.getSettings is not working.

Does the microsoftTeams js library works for Outlook too? If not how do I do?

It seems that Connect To Office 365 Button aren't the ongoing way to do it.

Documentation with dead links and mix between Teams & Outlook doesn't help :(

Thank you!

Edit 1:

AngularJS code called on my configuration page:

    $scope.setValidateState = function() {
        microsoftTeams.settings.setValidityState(true);
    };

    $scope.authenticate = function() {
        microsoftTeams.authentication.authenticate({
            url: isSettings.serverUrl + '/microsoft/auth-start/',
            with: 500,
            height: 800,
            successCallback: function(data) {
                $scope.isAuthenticated = data && data['accessToken'];
                localStorage.setItem("microsoft-oauth", JSON.stringify(data));
                displayConfiguration();
            },
            failureCallback: function(reason) {
                console.log(reason);
            }
        });
    };

    function displayConfiguration() {
        microsoftTeams.settings.setValidityState(true);
        microsoftTeams.settings.registerOnSaveHandler(function(saveEvent) {
            microsoftTeams.settings.setSettings({
                entityId: 'icescrum-connector-pkey-' + $scope.settings.project.pkey,
                contentUrl: isSettings.serverUrl + '/microsoft/setup/',
                configName: $scope.settings.project.name
            });
            microsoftTeams.settings.getSettings(function(settings) {
                $scope.settings.webhookUrl = settings.webhookUrl;
                console.log(settings.webhookUrl);
                saveEvent.notifySuccess();
            });
        });

        microsoftTeams.settings.getSettings(function(settings) {
            $scope.setup = !settings.configName;
            ProjectService.listByUserAndRole(Session.user.id, 'productOwner', {light: true}).then(function(projects) {
                $scope.projects = projects;
                if (settings.entityId) {
                    $scope.settings.project = _.find($scope.projects, {pkey: settings.entityId.split('icescrum-connector-pkey-')[1]});
                }
                $scope.ready = true;
            });
        });
    }

    // Init
    $scope.settings = {};
    $scope.projects = [];
    $scope.ready = false;
    var tokenData = JSON.parse(localStorage.getItem("microsoft-oauth"));
    $scope.isAuthenticated = tokenData && tokenData['accessToken'];

    microsoftTeams.initialize();

    if($scope.isAuthenticated){
        displayConfiguration();
    }

My microsoft Teams js lib was outdated (1.3.4). With the last version (1.4.1) it works well on Outlook and on Teams.
