The product "RE900XD Wi-Fi 6 WLAN Repeater AX6000" can be used as an access point, as it can be operated in access point mode. To use it with Yallo Home Max Fibre, you must ensure that the repeater is correctly configured as an access point and that an Ethernet connection to the router is established. It is important to check the DHCP settings and make sure that the repeater receives the correct IP address. If you have any problems, I recommend consulting the manufacturer's instructions or looking for support in the TP-Link forum.
