Provide total tokens staked through Token API
Motivation It would be very useful to have historical information about staked amounts on the portal dashboard page. This is the second ticket in series of tickets related to adding total staked ASTR/SDN on the dashboard page. Depends on #753
Suggested Solution
Create a new endpoint /api/v1/:network/dapps-staking/staked/:period on [Token API service](https://github.com/AstarNetwork/astar-token-api). The endpoint should fetch tokens staked data from deployed indexer (see #753) GraphQL endpoint and provide results in form:
[timestamp, staked_value][]
Alternatives Not at the moment. Any ideas are welcome.
Additional Information Please comment if the ticket is not clear enough.
Hi , I have a question regarding the UI DAO Ambassador Task. I worked on task 754, where I cloned the repository and added a new endpoint to the URL (see screeenshot). However, I realized that the necessary data cannot be retrieved without an indexer, which means that task 753 needs to be completed first.

I am not familiar with working on an indexer, so I am unsure if I am capable of handling it. Should I complete task 753 before moving on to 754? Or is it possible to work on the 754 task, even if the API has not the necessary indexer in place?
Another suggestion. Why leave a input field for a string for a api query which only has 2 possible parameters? Would it not be better do it as a dropdown? Like that?
