I have an old java server that embeds CSRF token into html page with .jsp in the following format:

<input type="hidden" name="_token" value="Some_Random_CSRF_Token_Value_Here" />

and there are multiple of these elements on html page. Site requires authentication/login, not sure if it is relevant though.

Some of the endpoints require CSRF token in order to interact with an endpoint.

I am trying to use these endpoints from React SPA I tried to fetch and then parse html to extract CSRF token, but that didn't help.

How can I interact with these kinds of endpoints?

Edit: Assume that I don't have access to modify server code.
