Teams (free) & Storage

According to the help document linked below, chat photos are stored for as long as you like!

Does anyone know if there's a storage limit for chat photos?  I'm not referring to content sorted in the OneDrive (Microsoft Teams Chat Files), I'm talking about general chat content that's not shorted in OneDrive.
