投影仪海报脚注中的脚注文本

Question

我正在使用此模板创建海报模板https://www.overleaf.com/latex/templates/yet-another-beamerposter-theme-with-variable-sizes-and-colour-themes-portrait-version/jgzfyrgpmvgk。我已修改文本正文，使其仅包含三个“宽列”块（即没有并排的列）。我想在海报正文中使用脚注，但让脚注文本出现在文档的脚注行中，作者和机构位于此处（我不需要，想删除）。目前，脚注文本出现在我最后一个宽列块的末尾和脚注行的顶部之间。我尝试修改以\setbeamertemplate{footline}替换，但它不起作用。非常感谢您的帮助！\insertauthor\footnotetext
