Material-ui: Micro Frontend Theme Problem

[ahmetcaglayan]

Hello,
I have multiple nested applications.
Each is compiled separately.
They come together in a large container.
But the button in the main application takes on the theme features.
When you add a button in the sub-application, the theme features go.

For the material button from the sub-application, how do I get the theme properties removed?
