BufEnter autocmd for DiffviewFiles

[simonmandlik]

Hello everyone, I'm using the following to hide the cursor when entering NvimTree and DiffviewFiles:

local function hide_cursor()
    vim.cmd [[
        hi Cursor blend=100
        set guicursor+=a:Cursor/lCursor
    ]]
end

local function show_cursor()
    vim.cmd [[
        hi Cursor blend=0
        set guicursor-=a:Cursor/lCursor
    ]]
end

vim.api.nvim_create_autocmd("BufEnter", {
    pattern = { "NvimTree*", "DiffviewFiles" },
    callback = hide_cursor
})

vim.api.nvim_create_autocmd("BufLeave", {
    pattern = { "NvimTree*", "DiffviewFiles" },
    callback = show_cursor
})

This doesn't work as the BufEnter event is never fired. What am I doing wrong? Thanks!
