please give ans. with refrence according to attached case study thank you.

Case - Oatly: Milk That Oat Oatly was founded by a scientist in Sweden who was looking for innovative and environmentally friendly alternatives to milk products. By 2016, Oatly had entered the North American market but mainly in the United States. Specifically targeting health food stores and higher-end coffee shops, Oatly's products were a hit with customers. Oatly's meteoric rise is partly thanks to introducing its product to coffee shops around the world. The company's main product is oat milk made in a relatively simple process of blending oats and water, adding some enzymes, and then removing fibres. What remains is a taste and consistency very close to cow's milk. As a result, the alternative product has been gaining awareness and popularity. The other reason for Oatly's success is the increased popularity of plant-based products. With consumers more able to wrap their heads around eating a Beyond Meat burger or breakfast sandwich, other food options become more palatable-with one critical requirement-that they taste good. If this condition is met, consumers today seem very willing to look at alternative products, especially ones that don't derive from a food supply that is heavily animal-focused. Despite the positive reviews of the taste and consistency of their oat milk, Oatly has struggled to create a stable foothold in the Canadian market. Even though awareness is high in the US and Europe, it struggles with its marketing communications in Canada. A CBC investigation looking into the popularity of oat milk included reference to Oatly as being a pioneer in the industry. Still, when it looked at the marketing of oat milk products, Oatly was not included. Therefore, Oatly has an incredible product, but its ability to raise awareness in Canada is low. please give answer of following questions in detail according to attached case study- 1. Define the marketing challenge for oatly. 2. Discuss in detail marketing, behavioral and communication objectives to maintain existing clients and to attract new clients to Oatly
