It's kinda hard to figure it out since you didn't provide more information about your case.

IINW, there's 2 type of text message in WhatsApp proto,
Conversation & ExtendedTextMessage

Conversation commonly used in regular chat message that doesn't use Disappearing timer and
then ExtendedTextMessage is a rich text message that can containText, Link preview, Ads, and other properties like quoting, forwarding, Expiration (for disappearing timer) .

Right.

You can use this function to check:

func hasTextMessage(msg *proto.Message) bool {
	extendedMsg := msg.GetExtendedTextMessage()

	return len(msg.GetConversation()) > 0 ||
		len(extendedMsg.GetContextInfo().GetQuotedMessage().GetConversation()) > 0 ||
		len(extendedMsg.GetText()) > 0
}
