To follow @ganfra 's remark, I would have let this if test at the calling place (i.e. in the init {} block) to reduce indentation in the body of this method. Also the method could then be renamed to fetchRoomSummary

// we can try to query the room summary api to get more info?

Maybe have a small method to map PeekResult to RoomSummary also?

Here we are copying an existing roomSummary with info from peekResult, so I think this is not applicable

// it's also possible that the name/avatar did change since the invite..
// if it's null keep the old one as summary API might not be available
// and peek result could be null for other reasons (not peekable)
avatarUrl = peekResult.avatarUrl ?: roomSummary.avatarUrl,
displayName = peekResult.name ?: roomSummary.displayName,
topic = peekResult.topic ?: roomSummary.topic
// maybe use someMembers field later?
)
)
)
}
}
else -> {
// nop
}
