How can we push data to analytics table on Cloud

We have requirement to create custom reports in insights for that i am trying to push some data to analytics table using analytics node but data is not getting reflected in analytics table.
If anyone has work on this earlier please help me to implement this one.
Plat :- cloud

  1. Use database node in a flow to send data to tables: Action Nodes |
  2. Use export option to export a csv file from your local system to cloud: Manage database tables & data |
  3. Use the tables data for visualising: Create custom queries for custom tables |
