I am using ncs2.6.1.
I built and run ot_cli based on ncs2.6.1, then I wanted to update openthread library so I modified openthread's revision on file nrf/west.yml

Then I updated west successfully.

After doing these, I built ot_cli again and burned the new firmware into my nrf52840dk board. But I found that the version of openthread didn't change.

So, what is the right way to update openthread library ?
