Here you are considered as Product Owner. Product Owner should be easily approachable and most likely to be sitting at the same place where the team is located [collocation]. This will INCREASE the collaboration between team and product owner and reduce a great amount of time in clearing team doubts about user stories.

He should be very transparent with respect to goals, aspirations and discussions.

• Location: A Product Owner should meet the team very often and in a very respectful and transparent manner.
• Issue discovery: When the  team discovers any issue then they should immediately inform the Product Owner to take the necessary decisions. Therefore, a PO is an empowered person who can handle these situations diligently instead of cribbing or shouting on the team.
• Requirement Change: In such cases, PO should transparently talk to the team to explain the business need of this change and how it will help the customer. Needless to say, this discussion will need to be backed up with a correct business justification, value GENERATION, time estimates and see if it fits the current sprint or not.
• Motivation with realistic asks: It is important to remember that commitment towards amount of work in a sprint is a Scrum team’s area of ownership. No one can force Scrum team to pick up more than they can deliver but a PO should try to motivate the team by SHOWING them how they can improve their velocity or value generated. PO can also pitch in while prioritization discussions to help take up important asks first. 
• Communicating Vision: PO should regularly communicate their vision of PROVIDING value to the customer and how the user stories will help achieve those to scrum team. It helps them get aligned with the vision and become part of your journey.
• Meetings: PO should be part of sprint planning, backlog grooming, sprint REVIEW, sprint retrospective meetings for sure. Regarding Daily scrum, their presence is not mandatory because they can refer to the Information radiators to see if the value is being generated.  If a PO wants to attend daily scrum meeting then they are welcome to do so but should be in a passive mode.
