You're almost there.

You only need to return object like { suggestions: suggestions } instead of array in your provideCompletionItems method and you're done:

monaco.languages.registerCompletionItemProvider('dummy', {
  provideCompletionItems: () => {
    var suggestions = [
      {
        label: 'simpleText',
        kind: monaco.languages.CompletionItemKind.Text,
        insertText: 'simpleText',
      },
      {
        label: 'testing',
        kind: monaco.languages.CompletionItemKind.Keyword,
        insertText: 'testing(${1:condition})',
        insertTextRules: monaco.languages.CompletionItemInsertTextRule.InsertAsSnippet,
      },
      {
        label: 'ifelse',
        kind: monaco.languages.CompletionItemKind.Snippet,
        insertText: ['if (${1:condition}) {', '\t$0', '} else {', '\t', '}'].join('\n'),
        insertTextRules: monaco.languages.CompletionItemInsertTextRule.InsertAsSnippet,
        documentation: 'If-Else Statement',
      },
    ];
    return { suggestions: suggestions };
  },
});
