I see the problem.
1- You can use the parameter flag=”term_name” to convert the id from the user meta into term names before the output.
2- You’re quering the user incorrectly.
object_id_type=”find” is used for finding a user through a meta query and you must also use the object_id=”field:value” to find the user. If you use the first parameter, you’re telling it to find a user, but without the later the plugin doesn’t have any parameters for the search.
For example:
[vg_display_data object_id_type=”find” object_id=”phone:1234″ key=”user_email” data_source=”user_data”]
Will find a user where the meta field phone=1234 and display the email of that user.
Note, we can only make a search based on one meta parameter.

In general, your use case is probably more advanced than what this plugin allows. You’ll probably need to code your own shortcode.
