Once you have added the text, you need to specify the timing of the subtitles. This is done by adding tt:start and tt:end tags to the text. The tt:start tag specifies the time at which the subtitle should start to appear, and the tt:end tag specifies the time at which it should disappear.
You can also use tt:style tags to specify the appearance of the subtitles. This can include things like the font, size, color, and position of the text.
