How to use the @aurelia/i18n.TranslationAttributePattern.registerAlias function in @aurelia/i18n

function setup(aliases: string[] = ['t']) {
    const patterns: AttributePatternDefinition[] = [];
    for (const pattern of aliases) {
      patterns.push({ pattern, symbols: '' });
      TranslationAttributePattern.registerAlias(pattern);
    }
    const container = DI.createContainer(AttributePattern.define(patterns, TranslationAttributePattern));
    return container.get(IAttributePattern);
  }
