How to get data from variable_value table of Custom Variables module

I need to get data from variable_value table – https://prnt.sc/19j4gk4

Then I need to change variable_id here to its name from parent table variable – https://prnt.sc/19j4to5

I want to get list of variables like that

id
2   TEST_var1_name  0   1       example html value
4   TEST_var1_name  1   NULL    example html value for another store

I know, that I can use Collection from variable table. But how can I get data from child table?
