SharePoint 2019 - communication site

Question

Hello!

I would like to know that, in SharePoint 2019 exist possibility to insert CSS file/code? I'm not an administrator, I'm just owner of communication site. Before migration I worked with SP2013, and there I used a script editor, but now it is impossible even to add script editor web part by admin(security reasons). If anyone knows or have an idea how to do this please let me know.
Can an administrator add for users/sites owners possibility to use script editor or script link? This require additional tasks from an administrator side ?

Br,
Mat

Hi @Mateusz Janyszko，

Script editor web part and the Content editor web part are not available in SharePoint modern page. As a workaround, you could use spfx in SharePoint 2019 to deploy css code.

SharePoint 2019 need some diferent version in the document. Please make a reference.

You could deploy the following solution to create a custom webpart which has the same function with script editor.
