The implementation of _attachThreshold() loops through each of the configured set of thresholds searching for the element that adjusts to the bridged amount. 
If no configuration is found the function will revert, the message will be lost and it will require manual handling. 
It is recommended setting a default value (a high value number of approvals) to be used when no threshold configuration matches.
