WWAN T14S支持，Modem-manager找不到调制解调器

Question

我有一个由联想直接提供WWAN卡的Thinkpad T14s (AMD)。调制解调器管理器似乎无法检测到卡？

然而，当我运行'Modem-Manager GUI‘时，我得到一个空白屏幕，

当我运行“mmcli”时，我会得到“没有找到任何调制解调器”。

我已经深入Linux 3年了，但这是我第一次使用WWAN笔记本电脑，所以我不知道从哪里开始。

我也从这个职位中看到，我至少不是一个人在挣扎，虽然我不确定最近是否有我错过的东西。我也注意到，其他类似的帖子正在谈论使用usb调制解调器，而不是内部卡，不确定是否有实际的区别。

Fibocom L 850-GL/ Intel的XMM7360 WWAN卡没有在我的Thinkpad上运行，也没有联想的任何支持。

有报道说人们在使用非官方磨料法GitHub的研制的WWAN卡上取得了成功.几年前，我的卡就开始工作了，但是只能手动加载驱动程序，这对于工作设置来说并不可靠。
