The "Create ClusterUserDefinedNetwork" has minor flaws:
1. The Match Labels should have red asterisk, since it's mandatory field
2. The placeholder should be "kubernetes.io/metadata.name="
3. [RFE] It would be more convenient to select namespace from the list, than to type it manually
4. [RFE] The term Project is not correct here, probably Namespace should be used

1. Navigate to UserDefinedNetworks page
2. Start CUDN creation
3. Add project matching label in the form of "kubernetes.io/metadata.name=namespace"
