ProcArrayGroupUpdate wait event in the database,

Hello Good Morning/Evening, we are using postgresql version 13 in our organisation, recent days we are seeing multiple occurrences of ProcArrayGroupUpdate wait events, and when this occurs, it slows down the entire database. I tried to search in internet for reason for this wait event, but i did not get any solution. could any one help on this? does this have any relationship with long running transaction? What type of statement will cause this wait event .(select , update, insert, delete?)? Thanks …
