When I tried to update private message, it has different 2 IDs:

1. ID of private message
2. ID with bigger number (like a ID for edit private message)

When I test to send PUT request, ID of private message just can change title. And can not change message details by “raw”

**It seems message details must change by new edit ID**  
**And I do not know how to get the second ID of the post (1846 in image)**

Could you explain for this issue?
