How can the Smarty plugin be used inside a plugin?

Question

Smarty

Hello. I got an old project that uses the Smarty template engine of the second version. Now my task is to translate the site into multilingual. So. Smarty plugins are displayed in many places in the template, for example:
{pluginname param1="value1" param2="value2"}
I wrote a smarty plugin that translates texts. I won't show the plug-in itself, because that's not the point of the question. In general, I need to do something like this:
{pluginname param1={translate section="ololo" message="Blablabla"}}
When I output in this form, the text is displayed accordingly, as I enter it. I tried in quotation marks - also no result.
I ask for help very much ^_^
