STEP 2-UPDATE/CHANGE AN EXISTING UIA
A UIA can be modified by the issuer after creation. For this, a separated call update_asset has been created.
WHAT CAN AND CANNOT BE CHANGED (?)
Except for
- Symbol
- Precision,
every parameter, option or setting can be updates.
Note : Once a persmission is removed, it can not be re-enabled again!
