Add Sygma transfer button to the demo scene.

[kalambet]

Summary
Add Sygma transfer button to the demo scene.

Suggested features or ways to address the summary
The current Demo Scene needs to be updated to add 1155 transfer example. Since the token contract address should be registered within the bridge beforehand - it can be hardcoded into the example.

Motivation
It would be beneficial to start building Sygma examples so developers will know what sequence of calls needs to be preformed to move entities between the networks.

Acceptance Criteria
The button and initial logic of the calls are presented. There is no need to complete wiring up and testing, however, the example button in the Demo Scene by default needs to be DISABLED.
