Automatic autorun of HTML code in the template cell

[nicozdeb91]

Hi all,
In the default user settings for each user, autorun is disabled, and the user using the notebook should not enable it.
I can't make autorun automatic with the format template.
In the template there is a simple Banner with a Link to an LSF job but it does not run, I tried with toml, I tried with other systems but the banner cell once the notebook is started I do not find it executed.
Do you have any suggestions on how I can make the banner display to the user automatically? I repeat it is not code but a simple Html banner that must be displayed as soon as the Marimo notebook is opened
