File upload in headless execution

Is there any other way that we can perform file upload in headless mode?

This is the source file of that file upload object.

div data-testid="DropZone" class="jss202">
   <div class="jss199">
      <div class="jss196">
         <div role="button" tabindex="0" style="height: 100%; width: 100%; justify-content: center; display: flex; align-items: center;">
            <input data-testid="dropZone" multiple="" type="file" autocomplete="off" tabindex="-1" style="display: none;">
            <div class="jss198">
               <span class="MuiButtonBase-root MuiIconButton-root jss205" tabindex="0" role="button" aria-disabled="false">
                  <span class="MuiIconButton-label">
                     <svg class="MuiSvgIcon-root jss204 MuiSvgIcon-colorPrimary MuiSvgIcon-fontSizeSmall" focusable="false" viewBox="0 0 24 24" aria-hidden="true">
                        <path d="M12 2C6.48 2 2 6.48 2 12s4.48 10 10 10 10-4.48 10-10S17.52 2 12 2zm5 11h-4v4h-2v-4H7v-2h4V7h2v4h4v2z"></path>
                     </svg>
                  </span>
                  <span class="MuiTouchRipple-root"></span>
               </span>
               <span class="MuiBox-root jss212 jss200">
                  <p class="MuiTypography-root jss206 MuiTypography-body1">Drag and drop files here, or click to browse</p>
               </span>
            </div>
         </div>
      </div>
   </div>
</div>

 When I use this code as below it's not working as it says that particular object not found

Aliases.uploadPage.FindElement("input[data-testid='dropZone']").SendKeys("path for file")

Is something wrong I am doing here?
