It is listed in the official Obsidian Community Plugins directory under the name LaTeX Autofill.
When writing math notes in Obsidian, the slow part is often not the math but remembering what the LaTeX is called.
LaTeX Autofill lets you type what you mean. Inside $…$ or $$…$$, type integral, matrix or partial (English or Chinese) and a completion list appears at the cursor. Press Enter and the full template is inserted: partial gives \frac{\partial f}{\partial x}.
