How can i remove other option from upload

i want to keep only Link option to upload document

How can i disable other option

This script customizes the file upload UI in Frappe Web Forms, by hiding unwanted buttons and configuration options such as “Link”, “Camera”, “Set all private/public”, and the optimize/private settings area after file selection.

It uses a MutationObserver to detect when DOM elements are dynamically inserted (e.g., after opening the file picker or uploading files) and hides specific buttons or sections.

frappe.ready(() => {
    
    const observer = new MutationObserver(() => {
        // Hide "Link" and "Camera" buttons
        document.querySelectorAll(".btn.btn-file-upload").forEach(btn => {
            const labelDiv = btn.querySelector(".mt-1");
            if (labelDiv) {
                const label = labelDiv.textContent.trim();
                if (label === "Link" || label === "Camera") {
                    btn.style.display = "none";
                }
            }
        });

		  // Hide "Set all private" immediately when popup appears
		  document.querySelectorAll('button').forEach(btn => {
            if (btn.textContent.trim() === "Set all private") {
                btn.style.display = "none";
            }
        });

        // Hide "Optimize" and "Private" config area after file selection
        document.querySelectorAll('input[type="file"]').forEach(fileInput => {
            fileInput.addEventListener('change', function () {
                const configArea = document.querySelector('.config-area');
                if (configArea) {
                    configArea.style.display = 'none';
                }

                // Hide "Set all public" button
                document.querySelectorAll('button').forEach(btn => {
                    if (btn.textContent.trim() === "Set all public") {
                        btn.style.display = "none";
                    }
                });

				
            });
        });
    });

    observer.observe(document.body, {
        childList: true,
        subtree: true
    });
});
