'flow' isn't currently enabled ../type.js file

[anyuruf]

Hello am a newbie with "web dev". Try to follow along the example code from graphql/examples/neo-push at master · neo4j/graphql · GitHub repository. I changed everything from typescript to javascript. Renamed all the files to *.js and removed any typescript code.
The types.js renamed from .ts
types.js : {
import { Driver } from "neo4j-driver";
import { OGM } from "@neo4j/graphql-ogm";

export type Context = {
ogm: OGM;
adminOverride?: boolean;
driver: Driver;
};
}

When I try to run the start script I get this error """

/api/src/gql/index.js: Support for the experimental syntax 'flow' isn't currently enabled (12:8):

10 | export const typeDefs = [User.typeDefs, Member.typeDefs, Comment.typeDefs];
11 |

12 | export type Context = {
| ^
13 | ogm: OGM;
14 | adminOverride?: boolean;
15 | driver: Driver;

Add @babel/preset-flow (babel/packages/babel-preset-flow at master · babel/babel · GitHub) to the 'presets' section of your Babel config to enable transformation.
"""

Basically am stuck can't install and configure flow. I there a way I could disable this feature?
Thank you in advance!

I run "npm install --save-dev @babel/plugin-syntax-flow" install syntax-flow pkg and enabled the plugin from the babel config by adding : ["@babel/plugin-syntax-flow"] to the plugin section.

My new error is " Exporting local "Context", which is not declared.
2 | import { OGM } from "@neo4j/graphql-ogm";

4 | export type Context = {
| ^^^^^^^
5 | ogm: OGM;

"
code: 'BABEL_TRANSFORM_ERROR'

Thanks in advance
