mother needs help with daughters funeral cost

I am trying to start a fund me account for my sister. As of this morning 12/19/2020 her daughter passed away. My sister was not expecting this or had any idea it was going to happen. She works full-time as a care giver, and was working when her daughter was taken to the hospital were she passed away. She is a single mother, and was doing everything she could to put a roof over there heads. All funds will go to pay for the funeral cost. Any help would be appreciated. Thank you for taking the time to read this.
