KeePassXC-Browser does not connect to browsers Deepin using flatpak kepassxc 2.4.6 on Deepin V20.2

Hello Deepin Team

This is my default browser, but at the moment I had to switch to another browser. So could you please help me with this issue together with the developers of the keepassxc 2.6.4 application and the KeePassXC-Browser extension 1.7.7.

Everything was working normally and suddenly after new installation of Distro Deepin V20.2 it stopped connecting the extension with the keepassxc app, as can be seen in the link below. Can browser and extension coexist in partnership of quality and mutual efficiency?

The browsers in question without exception are the Chromium base, where after updating the extension that these problems began to occur. Everything leads us to believe that it is the browser extension that does not connect with keepassxc 2.6.4.

Thank you in advance for your attention
