The logo guidelines of the Wireless Power Consortium state that products that do not have magnets must still be marketed with the old Qi logo. So if you want to buy a Qi2 product with support for magnetic accessories, you only need to look out for the Qi2 logo. In practice, it may not always be quite so simple.
. According to this table, the logo originally intended for Qi2 designates products that do not support magnets, while the same logo framed by a circle was intended to denote the Magnetic Power Profile.
Since this logo (Qi2 in a circle) has been used rather sporadically in the past, a Notebookcheck editor spoke to one of the companies responsible at CES. Accordingly, it is an outdated logo that will no longer be used. This can be seen in the HMD Skyline, the first Android smartphone with support for Qi2, including Magnetic Power Profile, which is marketed with the Qi2 logo without the circle.
HMD Skyline supports QI2 with magnets but uses the logo without the circle. So, basically anything marketed with QI2 may or may not support magnetic attachment like magsafe.
You would need to confirm by checking the product database or reviews to know if the smartphone or accessory actually supports Magnetic Power Profile QI2
