Friend has just had a stillbirth at 35 weeks. She has COVID. How do I help her..

After years of trying and finally getting pregnant my best friend just messaged me saying she’s just had a stillbirth at 35 weeks, today. She just found out an hour ago. She has COVID and she hadnt felt it move.. she was so far along. Then couldn’t find a heartbeat. What do I say to her. Any experiences or anyone comfortable with sharing?
