What do you see as an issue?

https://airflow.apache.org/docs/apache-airflow/stable/howto/customize-ui.html

from airflow.www.utils import UIAlert

DASHBOARD_UIALERTS = [
    UIAlert("Welcome to Airflow"),
]

should be replaced by

from airflow.api_fastapi.common.types import UIAlert

DASHBOARD_UIALERTS = [
    UIAlert(text="Welcome to Airflow", category="info"),
]

Hi! I can take this issue.
I will update the docs example to use from airflow.api_fastapi.common.types import UIAlert and update the code snippet accordingly.
I’ll open a PR shortly.

Hi folks I updated the Customize UI docs to use the current UIAlert API:

• Import from airflow.api_fastapi.common.types
• Use keyword arguments (text, category) in static and dynamic examples
• Added a short clarifying note

PR: #58540

Two small asks:

1. Could a maintainer please approve the workflow runs so CI can complete? (This is a fork PR.)
2. Could someone on the docs team take a quick look? I’ll push any tiny wording/formatting fixes immediately.

Thanks!
