Prevent Flask from changing the url from '/home' to '/static/home'

Question

The app runs only when I build the angular project using ng build --base-href=/static/ but then http://127.0.0.1:5000/home automatically changes to http://127.0.0.1:5000/static/home and the rest of my routes fail, even a refresh button fails as /static/ route does not exist in my angular routing.

app-routing.module.ts

{ path: 'home', component: HomeComponent },
{ path: 'demo', component: DemoComponent },
{ path: '**', redirectTo: 'home' }

index.html

<base href="/">

angular.json

  "root": "",
  "sourceRoot": "src",
  "prefix": "app",
  "architect": {
    "build": {
      "builder": "@angular-devkit/build-angular:browser",
      "options": {
        "outputPath": "../static/",
        "index":{
          "input": "src/index.html",
          "output": "../templates/index.html"
        }

server.py

app = Flask(__name__)

@app.route('/')
def root():
    return render_template('index.html')

@app.route("/home")
def home():
    return render_template('index.html')

if __name__ == '__main__':
    app.run(port=5000, debug=True)
